Reusing some previous assignments does not work

[sratanota]

I'm trying to reuse assignment from last year. However after selecting organization and class, I received this error

I also haven't been able to reuse assignments from a previous classroom (same org). I didn't see any error message though, but only one out of 15 assignments was imported/reused successfully, the one without a template.

Same thing: several attempts to reuse assignments within the same org does not work, and leaves no error message. It just ends up displaying the classroom dashboard page after a while. No success at all, whether when trying to reuse several or just one assignment from a different classroom.

I still have the same problem. When could this be fixed?
