TypeError: array_diff(): Argument #2 must be of type array, null given in array_diff()

Updating issue meta data.

If this problem was discovered on a version of Drupal that is not 11.x, add that information in the issue summary and leave the version at 11.x. In Drupal core changes are made on on 11.x (our main development branch) first, and are then back ported as needed according to the Core change policies → .

Also, un-assigning per Assigning ownership of a Drupal core issue → . And finally, restoring standard issue template → . The issue template is used to track progress and tasks on an issue.

I’ve opened a merge request. The config import (cim) breaking issue is now resolved.

Moving it to `Needs Review` state.

Thanks
