When I add a group or want to edit a group member I get the following error:

Warning: Undefined array key "group" in Drupal\group\Entity\Access\GroupRelationshipAccessControlHandler->checkCreateAccess() (line 61 of modules/contrib/group/src/Entity/Access/GroupRelationshipAccessControlHandler.php).

Unfortunately the actual problem is upstream of the error, so we can't tell you what would cause this. Do you have any custom modules installed? Usually issues like this will start there.

Otherwise, take a backup then start deleting modules until the problem goes away, to try to determine which module is causing the issue. Then you can hone in on it from there.

Contact me to contract me for D7 -> D10/11 migrations.

Hello tomhorn,

The Undefined array key "group" error in the GroupRelationshipAccessControlHandler usually indicates a mismatch between the entity type and the group membership data, often triggered when a relationship is being accessed without a valid group context.

Before deleting modules, I recommend trying these specific steps:

  1. Clear all caches: Use drush cr if you have terminal access.

  2. Rebuild Permissions: Go to /admin/reports/status/rebuild and rebuild permissions.

  3. Check for Updates: Ensure the 'Group' module and its sub-modules are on the latest stable version compatible with Drupal 11.x.

  4. Database Check: Verify if there are any orphaned records in your group_relationship tables.

If these steps don't resolve it, it might require a deeper dive into your custom entity configurations. My team at Yiion Systems specializes in debugging complex Drupal 11 backend issues and access control errors. We can help you identify the exact root cause and fix it professionally.

Are you using entity_clone perhaps?  https://www.drupal.org/project/group/issues/3328924#comment-16420779
