Description

This happened not the first time to me today, that the scheduler backend module throws just a white page. We could always solve this by cleaning out the task-records from the scheduler tasks table in the database.

Proposed change:
Make it a bit more robust to detect this problem, show a warning message

Indeed this was improved already in the past, but apparently not enough. One typical situation is if a task's class signature has changed since it was first serialized.

I'll try to take a look at some point.

Hi Mario,

I finally took a look and I couldn't trigger such a mishap. Could it be related to #33116? Could you provide a test scenario?

I don't think it's directly related to #33116 by reading the bug report.

Also I'm not 100% sure what triggered the error. But I think it was one of the following:

the scheduler task's class was removed (and the task record still points to it)
the scheduler task's class was renamed (and the task record still points to the old name)
