Known issues in Cloud IDE

This page describes any known issues with Cloud IDE.

If you encounter any difficulties with Cloud IDE, contact Acquia Support for assistance.

Only one IDE can be used at a time

If you’re working with multiple IDEs simultaneously, you might receive the following error message when performing an action that requires invoking a Cloud Platform API endpoint. For example, when using Acquia CLI.

Your Cloud Platform API credentials are invalid.

It happens because at the moment only one IDE at a time can be authenticated against the Cloud Platform API. To work around this issue, ensure that only one IDE is opened in a browser tab at any given point in time.

Git operations with the remote fail from within the Git user interface

In Cloud IDE, the Theia Git UI integration has a known limitation related to not accepting SSH key passphrases. As such, any operation with the remote fails (namely pull, push and fetch). To ensure that your application is secure at all times, Acquia recommends that you use Git from the command line to interact with the remote until this bug is resolved upstream.

Cloud IDE is incompatible with database prefixes

In Cloud IDE, Acquia preconfigures your database connection so that you can run your application without requiring manual configuration of the Drupal database array. However, if you use database prefixes, Acquia cannot detect this custom setting and you must configure the Drupal database array manually in settings.php.

Downloading a large database through the visual database editor can fail

The visual database editor offers the option to generate and locally download a MySQL backup of your tables. Due to the very nature of PHP processes and fixed timeouts across the stack (Apache and nginx), it is normal that databases larger than a few hundred megabytes will fail to download.

The best practice to download a database backup from Acquia Cloud Platform is to leverage Acquia CLI, by using the pull:db --no-import command. Alternatively, to download the IDE database, use Drush or a raw MySQL command instead.

Pulling an application times out when the Shield tunnel is down

In Cloud IDE, pulling an application times out with the following error when the Shield tunnel is down.

ssh: connect to host port 22: Connection timed out

To prevent this issue, use a network monitoring tool to generate keepalive pings. For more information, see resolving Shield issues.

Sending emails from Cloud IDE doesn’t work

Sending emails from Cloud IDE is not currently supported. As a workaround, you can use an external SMTP relay.

Xdebug does not work with PHP 8

PHP 8 is compiled with Xdebug 3, which is currently not preconfigured in Cloud IDE. Acquia will soon make the necessary adjustments so that Acquia CLI takes care of this automatically for you when enabling Xdebug. As a workaround, you can load the correct configuration file yourself by completing the following steps:

  1. In the Cloud IDE menu bar, click Terminal > New Terminal

  2. Disable Xdebug if it is enabled:

    acli xdebug
    Xdebug PHP extension disabled.
  3. Load the Xdebug 3 configuration settings:

    export PHP_CONFIG="/home/ide/configs/php" && \
    mv $PHP_CONFIG/xdebug.ini $PHP_CONFIG/xdebug2.ini && \
    mv $PHP_CONFIG/xdebug3.ini $PHP_CONFIG/xdebug.ini
  4. Enable Xdebug:

    acli xdebug
    Xdebug PHP extension enabled.


To revert the changes, follow the same steps but load the Xdebug 2 configuration settings instead.

export PHP_CONFIG="/home/ide/configs/php" && \
mv $PHP_CONFIG/xdebug.ini $PHP_CONFIG/xdebug3.ini && \
mv $PHP_CONFIG/xdebug2.ini $PHP_CONFIG/xdebug.ini

Dark Reader browser extension runs into API limits

The Dark Reader browser extension (Chrome / Firefox) increases the number of HTTP requests per page load as it analyzes images and sends them to a third party to see if the colors should be inverted. This results in too many API requests to the IDE proxy and display the following error:

    "error": "rate_limit_exceeded",
    "message": "You have reached the maximum number of requests to the API. Please try again later."

Vimium browser extension might break the IDE functionality

The Vimium browser extension (Chrome / Firefox) provides keyboard shortcuts for navigation and control in the browser. It might break the IDE functionality, such as the Vim editor in the terminal. Acquia recommends disabling the Vimium browser extension by creating a rule.

To create a rule, go to Vimium Options, and add the following URL in the “Patterns” field. Click Add Rule, and then click Save Changes.
