If you alter the content type configuration for a content type that you are exporting to Content Hub, search mappings for that content type may no longer correctly function. For example, after changing a field from a list of names to an entity reference, the field now cannot be used by Content Hub or indexed by the Elastic Search Index.

To address this, you can use the ach-reset [entity_type] Drush command to clear all entities of that content type from Content Hub, reset that content type’s mapping, reindex all entities of the specified type, and then republish them back to Content Hub.

For ach-reset [entity_type] to fully remove, reindex, and republish all entities of a certain type, it must be executed twice. Before executing, the command performs the following tests as a fail-safe to determine whether or not resetting and reindexing can proceed:

Does this website have a registered webhook for notifications?

Without a registered webhook for notifications after the reindex completes, the content will never begin the republishing process.

Is this entity type in use by multiple websites?

If yes, removing content will affect only content published by this website, because a website cannot delete other websites’ content. You must manually delete the content from the other websites using other means, such as the ach-delete command. The ach-reset command will provide you with a list of matching entities and their originating websites.

Has the reindex state variable been set to** Reindex Completed?

When a reindex request is sent, the reindex variable is set to Reindex Sent, and until the webhook notifies the website that the reindexing process is complete (setting the variable to Reindex Completed) Content Hub will accept no additional reindexing requests.
