Cloud Platform
Known issues in Cloud Platform
This page describes the known issues in Cloud Platform generally and Cloud Classic specifically. For known issues that are specific to Cloud Next, see Known issues in Cloud Next.
Using PHP 8.4 may cause deprecation warnings and Composer conflicts with certain Drupal and Drush combinations, such as Drupal 10.4.5 with Drush 13.4. This occurs due to incompatibilities with vendored packages or conflicting package versions.
If a new Cloud Platform environment is provisioned by a CI/CD process, such as Acquia Pipelines or Acquia Code Studio, the new environment is provisioned with the default Cloud Platform PHP version. The new environment does not inherit the PHP settings from the source environment or CI/CD build. For more information on the default PHP version, visit default Cloud Platform PHP version.
Workaround: You must set your desired PHP version for the new environment. You can configure the PHP version through the Cloud Platform user interface or the command line.
Cloud Platformacli app:task-wait "$(acli api:environments:update $TARGET_ENV_ID --lang_version=8.1)" PHP 8.4 is only compatible with Drupal 10.4 and higher and Drupal 11.1 and higher. Drupal 7 is incompatible with PHP 8.4.
PHP 8.3 is compatible only with Drupal 10.2 or higher. For more information, see https://www.drupal.org/docs/getting-started/system-requirements/php-requirements.
pcntl_fork() is not supported in live code and can cause stability issues with PHP 8 and later.Using the pcntl_fork() function with PHP 8 and later in website code can leak PHP processes. This crashes the site slowly. Acquia recommends that you do not use this function, as it might be disabled eventually. However, you can use it in CLI PHP scripts.
Using the Drush aliases from the Drush page in the Cloud Platform user interface might generate warnings with certain Drush commands if the site is running PHP 8.0.

drush-script: drush9The preceding block shows a sample Drush alias in the YAML format. If you run the drush uli command from your terminal, you might encounter the following warnings and deprecated messages:
$ vendor/bin/drush @default.dev uli
[warning] Undefined property: Drush\Commands\core\LoginCommands::$uri ExecTrait.php:38
[warning] does not appear to be a resolvable hostname or IP, not starting browser. You may need to use the --uri option in your command or site alias to indicate the correct URL of this site.

It typically returns a response within seconds, but sometimes can take several minutes to reflect the current state of the platform.
When inspecting the output of any successful or failed task, the final line is: zlib(finalizer): the stream was freed prematurely. This message can be ignored.
The acceptable file listing on the customer-facing ticket submission page lists XML as an acceptable file type, but XML files are not accepted for upload.
Workaround: Place the XML in a .zip file, and then attach the .zip file to the ticket.
The active domain for an environment defaults to the first bare domain name, with or without the www prefix, and cannot be changed. Environments that have no top-level custom domains use the Acquia default domain as the active domain.
When you use environment variables in the Cloud UI, starting a sequence with $ followed by a number removes the first two characters.
For example, adding $23456 as an environment variable results in 3456.
Workaround: When you use the environment variable in your code, manually prepend the first two characters to the variable. Acquia recommends that you validate your code to prevent any application issues when the issue is resolved.
Git checkouts fail with the following error when non-text files contain a specific byte sequence and are not explicitly defined as binary files: Your local changes to the following files would be overwritten by checkout. Please, commit your changes or stash them.
Workaround: Edit the following section of your .gitattributes file:
# Auto-detect text files, ensure they use LF.
* text=auto eol=lfand then make one of the following changes:
*.eol=lf text.Cloud Platform does not allow you to delete branches that are currently deployed to an environment. If you try to delete a branch from the command line, an error message like the following displays:
remote: Operation rejected: remote: Git branch or tag test_branch cannot be
deleted because it is currently deployed to testsite.prodWhen attempting to push code, some users may encounter error messages like the following example if the root account owns a directory, instead of the siteuser account:
remote: error: insufficient permission for adding an object to repository
database ./objects To correct the ownership settings for the directory, create a Support ticket.
Cloud Platform does not support the use of deployment keys (machine keys) that are not associated with an individual user account. All SSH keys must be associated with a user account.
Workaround: Create a user account to associate the deploy key as described in Deployment keys and Cloud Platform.
You might get a 404 error when you log in through Acquia Connector.
Workaround: You must assign the Access to legacy product keys permission to your role and re-authenticate yourself.
In non-hosted applications, only users with admin privileges can click the Sign in with Acquia option for authentication to the search functionality. Non-admin user roles like team lead and developer cannot access this option.
Upgrading to Acquia Connector 8.x-1.17 introduces the following error and may interfere with cron runs:
Call to a member function getEditable() on null Workaround: Acquia recommends that you revert to Acquia Connector 8.x-1.16.
See Upgrading to acquia_connector-8.x-1.17 can throw error “Call to a member function getEditable() on null” during cron runs for more information.
Drupal websites connected to Acquia subscription will send heartbeat requests during each cron run. By default, cron runs at the beginning of each hour, which can cause the Acquia subscription service to receive thousands of simultaneous connections across all subscriber websites. This causes some requests to time out.
Workaround: If your subscription service is experiencing timeouts, Acquia recommends that you modify your cron runs to not begin at the start of the hour.
The Acquia Connector module has a conflict with the Remote stream wrapper module, which is listed on the Modules to use with caution on Cloud Platform page.
Workaround: Apply this patch, available on Drupal.org.
The drush uli command works and returns the desired output even with the warnings. If these warnings block your development, remove the following segment from the yaml file:
paths:
drush-script: drush9 The current Drupal version is not compatible with the following legacy commands:
ah-db-backup: Drush command for creating a database backup from the command line.ah-db-import: Drush command for importing databases from the command line. For more information, visit Downloading database backups from the command line or Importing your database.ah-site-archive-import: Drush command for importing a website archive file, as described in Importing an existing application using Drush.drush archive-dump: Drush command for creating a complete archive file of your application, as described in Taking backups.You must use Composer to build websites running the current Drupal version. You cannot use Drush to update your Drupal websites.
If you are using Drush 9 in a Platform environment, Cloud Platform may display the following errors, such as:
Fatal error: require(): Failed opening required '/var/www/site-php//D8--[sitename]-settings.inc'Drush command terminated abnormally due to an unrecoverable error.Workaround: To determine if this Drush 9-based behavior is affecting your use of the product, execute the following commands from a command prompt:
drush9 php-eval 'var_export($_ENV['AH_SITE_NAME'] , true);'
printenv 'AH_SITE_NAME' These values must be equal. If they are not:
settings.php file.$_SERVER['PWD']=DRUPAL_ROOT;.settings.php file.Drush aliases for Cloud Platform CD environments are downloaded only if the environment is active.
Installing Drush in your user directory can cause unexpected task failures. Acquia recommends that you require a site-local Drush as part of your codebase, not your home directory, and run your commands with a specific major version of Drush, as described in Using Drush on Cloud Platform.
Cloud Platform displays the following error message while running Drush 12 commands:
/bin/bash: /app/vendor/drush: No such file or directory
The Drush alias files that Cloud Platform generates are not compatible with Drush 12.
Workaround: Update the Drush alias files as follows:
paths:
drush-script: '/var/www/html/${AH_SITE_NAME}/vendor/bin/drush' Legacy alerts from New Relic fail with the removal of TLS 1.0 from Acquia systems. For help in updating your alerts, visit Introduction to alerts and applied intelligence.
Website duplication can cause rsync issues in the distributed file system which results in the following log error:
rsync warning: some files vanished before they could be transferred (code 24)at main.c(1183) [sender=3.1.1]
Could not rsync from [error] Workaround: Create a Support ticket and specify the affected files listed in the rsync error.
The Cloud Platform CDN does not support the use of custom Varnish configurations (custom VCLs) with Cloud Platform-hosted applications. Attempting to do so can cause Cloud Platform Enterprise to experience conflicting caching behavior.
When requesting the Acquia default domain, the subscriber’s self-service SSL certificate loads instead of the Acquia SSL certificate that covers the Acquia default domains. This behavior causes an SSL error in the browser. Install and activate two or more custom certificates on any affected environment to remove this error on the Acquia default domain.
If a Drupal module logs information with the RFC 5424 severity of emergency, syslog broadcasts the information to open SSH sessions. These broadcasts can disrupt commands in progress, as indicated in the following example:
Broadcast message from [email protected] Workaround: Either modify the module’s logging function to decrease the message’s severity from emergency to another level, or disable the module’s logging feature.
The design of the Acquia platform can sometimes cause incompatibilities with Drupal contributed modules. Drupal modules not supported on Cloud Platform are listed in Modules and applications incompatible with Cloud Platform. Other modules usable on Cloud Platform with caution or special configuration are listed in Modules to use with caution on Cloud Platform.
Subscribers upgrading their websites to newer versions of the current Drupal version, must rebuild website caches after the upgrading. Unexpected errors and problems with some page displays may occur until you rebuild caches.
Attempting to run update.php on the current Drupal version fails with the following error message:
In order to run update.php you need to either be logged in as admin or have
set $settings['update_free_access'] Workaround: Use one of the following methods:
drush updb to complete database updates.update.php, use your browser’s cookie manager to grab the session cookie from your current authenticated Drupal session, and then remove the leading S from the session name.settings.php file to temporarily set $settings['update_free_access'] to TRUE during your updates.ADVANCED: Add the following code to your update.php file (directly following the use statements) to force Drupal to acknowledge the X-Forwarded-Proto value when determining if the request must be treated as HTTPS:
if (isset($_SERVER["HTTP_X_FORWARDED_PROTO"]) &&
$_SERVER["HTTP_X_FORWARDED_PROTO"] == "https") {
$_SERVER['HTTPS'] = 'on';
} Websites that alter the $databases array in settings.php to enable third-party database connections may experience connection errors when the connection setup is delayed in settings.php.
The Cloud Platform user interface does not support importing a website archive from a local file. Instead, you can import a site archive from a URL or import using Drush.
Clearing a website’s Twig caches clears the Twig caches for all websites hosted by that environment. For more information about how Cloud Platform stores Twig caches, visit Twig caches.
Resolution for Site Factory subscribers: Upgrade your installed version of the Site Factory Connector module to either version 8.x-1.59 and later, or version 8.x-2.59 or later (for Drush 9 support).
When you change themes and perform a code deployment on Cloud Platform applications running the current Drupal version, you might experience issues where cached Twig templates fall out of sync on different web infrastructure. The problem arises from having separate copies of the compiled Twig templates on each web infrastructure and a related Drupal core issue.
Workaround: When you make changes to themes in Cloud Platform Enterprise applications running the current Drupal version, connect to each web infrastructure, and run the following command to remove the outdated Twig templates:
drush @[sitename].[prod] --uri=http://[site_URL]/ ev '\Drupal\Core\PhpStorage\PhpStorageFactory::get("twig")->deleteAll();' The AuthUserFile directive in the Apache .htaccess file sets the name of a text file containing a list of users and passwords for user authentication. Cloud Platform does not support AuthUserFile, since its value must be either an absolute path or a path relative to the infrastructure root, and will not work across different Cloud Platform environments.
Due to the configuration of directory ownership and permissions for your Cloud Platform application’s codebase and files directories, the SymLinksIfOwnerMatch option in your application’s .htaccess file prevents your web infrastructure from accessing any of the assets in your files directory. You must use the FollowSymLinks option instead.
Do not use the LOGNAME environment variable to determine sitegroup or sitename in your .htaccess file or in other custom scripts.
Workaround: Use the AH_SITE_NAME, AH_SITE_GROUP, or AH_SITE_ENVIRONMENT environment variables if you need environment-aware variables in your scripts.
If you run mysqldump on MySQL 5.7, the following error occurs:
mysqldump: Error: 'Access denied; you need (at least one of) the PROCESS privilege(s) for this operation' when trying to dump tablespaces Workaround: If you do not need to dump the tablespace information, invoke mysqldump with the –no-tablespaces option.
When log forwarding is configured with a destination that includes an IP allowlist, the Cloud Platform user interface might display an error message for the inactive load balancer that indicates a connection issue or incorrect configuration. This occurs because the inactive load balancer uses a dynamic IP address until it becomes active. However, log forwarding from the primary or active load balancer functions correctly.
The New Relic APM PHP extension is incompatible with Drupal 11.3 and later due to missing support for the Fibers PHP feature. Drupal 11.3 and later use Fibers to improve performance. Therefore, requests using Fibers are not displayed accurately in New Relic. Any sub-requests may not be traced, and transaction data may not be accurate.
PHP 8.4 includes OpenSSL 3.x, which has strict TLS security requirements. This impacts all operations that require SSL connectivity. For example, when you attempt to perform system backups in FedRAMP applications, you might get the following error:
AWS HTTP error: cURL error 35: TLS connect error: error:03000072:digital envelope routines::decode errorWorkaround: If FIPS is enabled for your application, do not upgrade to PHP 8.4.
You might not be able to download the MySQL slow query log through the Cloud Platform user interface.
Workaround: You can check the MySQL slow query log stream and note the queries that cause issues. When you optimize a few of such queries, the log size is reduced. Thereafter, you can retry downloading the MySQL slow query log.
If you delete a backup manually, the backup continues to appear in the list on the Databases page for about 24 hours.
When downloading database backups using the Cloud Platform API v2, users experience failures if an Elastic Load Balancer (ELB) is present.
Workaround: If the ELB is not in use, create a Support ticket and request to have the ELB removed.
In the legacy Cloud Platform interface, when a user selects Resize > Cancel, occasionally the Cancel button does not dismiss the dialog box.
For Chrome version 87 or later, mixed content downloads were disabled. Owing to this, database backup downloads initiated in the Cloud user interface fail in some cases.
Workaround: The Cloud Platform user interface displays the http version of the db backup download URL. You can specify this URL in a new browser window to restart the download.
Cloud Platform Enterprise subscribers who use GNU Midnight Commander can experience service interruptions when trying to access their GFS mount. Acquia currently recommends that you do not use Midnight Commander with your Acquia-hosted websites.
After adding an access control list to your Varnish configuration file, you may not be able to download database backups through the Cloud user interface. It happens because while limiting access to your sites, your access control list also limits access to your Acquia default domain, such as example.prod.acquia-sites.com, that is required for database downloads to function.
To perform database backups:
You cannot generate certificate signing requests (CSRs) for Node.js classic applications through the Cloud Platform user interface.
Workaround: Upload SSL certificates manually.
The Cloud Platform multi-region failover service supports only a single database per environment.
When you enable FIPS in a Cloud Classic environment, certain applications and methods might break. For example, Ruby might fail with the following error:
FIPS mode is enabled, bundler can't use the CompactIndex API
Workaround: Modify your application to use only FIPS-approved cryptographic methods and avoid using methods like md5 that are prohibited in FIPS. For more information about FIPS-approved cryptographic methods, see supported methods.
Stack Metrics in the Cloud Platform user interface might display incorrect storage value. This value might be different from what you see when accessing the platform through SSH.
Workaround: Use SSH to access /mnt/gfs to get the accurate data.
SQLite extensions are not supported on Cloud Platform.
Cloud Platform is optimized for a managed MySQL-compatible database layer. Applications that try to use SQLite will encounter compatibility issues or fail to operate within the platform's infrastructure.
Workaround: Applications that require SQLite must be refactored to use MySQL-compatible databases supported by the platform.
This issue applies to Cloud Platform customers on shared infrastructure.
Cloud Platform is designed for cost-efficiency and flexibility. Because the platform uses shared infrastructure such as shared load balancers, Acquia prioritizes immediate service restoration. To bring sites back online quickly, Support engineers often restart or fail over affected hardware. This process frequently clears the low-level system state needed for a definitive Root Cause Analysis (RCA). You receive an incident summary that describes the restoration steps. However, you might not receive a detailed forensic RCA or a single-fix preventive guarantee.
Workaround : While platform architecture cannot be changed at the user level, you can reduce the impact of shared infrastructure incidents through Optimizing application performance by:
Enable Drupal page, block, and view caching.
Review cron jobs, database queries, and queues for long-running operations to improve efficiency.
Avoid uncached external API calls during the request cycle.
If this content did not answer your questions, try searching or contacting our support team for further assistance.
The Cloud Platform notification API does not display real-time results. It typically returns a response within seconds, but sometimes can take several minutes to reflect the current state of the platform.
When inspecting the output of any successful or failed task, the final line is: zlib(finalizer): the stream was freed prematurely. This message can be ignored.
The acceptable file listing on the customer-facing ticket submission page lists XML as an acceptable file type, but XML files are not accepted for upload.
Workaround: Place the XML in a .zip file, and then attach the .zip file to the ticket.
The active domain for an environment defaults to the first bare domain name, with or without the www prefix, and cannot be changed. Environments that have no top-level custom domains use the Acquia default domain as the active domain.

FIPS mode is enabled, bundler can't use the CompactIndex API
Workaround: Modify your application to use only FIPS-approved cryptographic methods and avoid using methods like md5 that are prohibited in FIPS. For more information about FIPS-approved cryptographic methods, see supported methods.
Stack Metrics in the Cloud Platform user interface might display incorrect storage value. This value might be different from what you see when accessing the platform through SSH.
Workaround: Use SSH to access /mnt/gfs to get the accurate data.
SQLite extensions are not supported on Cloud Platform.
Cloud Platform is optimized for a managed MySQL-compatible database layer. Applications that try to use SQLite will encounter compatibility issues or fail to operate within the platform's infrastructure.
Workaround: Applications that require SQLite must be refactored to use MySQL-compatible databases supported by the platform.
This issue applies to Cloud Platform customers on shared infrastructure.
Cloud Platform is designed for cost-efficiency and flexibility. Because the platform uses shared infrastructure such as shared load balancers, Acquia prioritizes immediate service restoration. To bring sites back online quickly, Support engineers often restart or fail over affected hardware. This process frequently clears the low-level system state needed for a definitive Root Cause Analysis (RCA). You receive an incident summary that describes the restoration steps. However, you might not receive a detailed forensic RCA or a single-fix preventive guarantee.
Workaround : While platform architecture cannot be changed at the user level, you can reduce the impact of shared infrastructure incidents through Optimizing application performance by:
Enable Drupal page, block, and view caching.
Review cron jobs, database queries, and queues for long-running operations to improve efficiency.
Avoid uncached external API calls during the request cycle.
