Found similar topic in knowledge base where  suggested solution is:

• Check if there are any deleted working sets recently.
• If it is possible, restore these working sets and then perform the export again.

See below link:

I don't know how to identify deleted working sets.

I am not an owner of tracker and only support user in his issue.

Maybe there is also another fix.

Codebeamer version 2.0.0.5

thank you
