Recently, I encountered a perplexing issue with Drupal: the dreaded error message stating, "The profile XXX does not exist." Despite attempting to clear the cache and even going as far as removing all cache tables, the problem persisted. Faced with this predicament, I found myself at a crossroads: either restore the database or delve into debugging to uncover the root cause.
Opting for the latter, I embarked on a journey to unravel the mystery behind this error. Upon scrutinizing the Drupal code, I made a crucial observation: Drupal utilizes cache and state mechanisms for storage purposes. Specifically, it employs the key system.profile.files for both cache and state functionalities.
If you find yourself encountering a similar issue, the initial step is to verify whether your profile exists within the profile list. To do so, execute the following command:
drush sget system.profile.files --format=json
If your profile is indeed listed, clearing the cache or truncating the cache tables might suffice to rectify the issue. However, if your profile is absent from the list, it's imperative to eliminate the corresponding state entry using the following command:
drush sdel system.profile.files
Or
Mysql Query:
SELECT * FROM `key_value` WHERE `name` LIKE 'system.profile.files'
By following these steps, you can effectively troubleshoot and resolve the perplexing "The profile XXX does not exist" error within Drupal.
