Steps to reproduce:
1) create a new user in admin
2) provide access authorization for Cockpit to the new user
3) login into cockpit with new user in Cockpit

Problem:
The backend returns an exception that the user is not allowed to fetch tasks per group. But the loading widget keeps loading (see attached screenshot)

Expected behavior:

• stop loading widget
• The exception is somehow unrelated, so that it is not clear where the problem is. To solve that the exception should not be displayed. Or the message contains more context that is related to "Assignments by group"
