Hi, I faced to an odd issue; while migrating some servers, keystone threw an exception and migration aborted
When I checked, a project with this ID does not exist, but the key point is it's not a project ID, it's an ID of a user.

I googled this problem but couldn't find more information except this [1].

PS: 
_ mysql logs were fine, didn't see weird queries
_ keystone works fine
_ openstack version kolla-ansible/train

Do you have any ideas?

Thanks,
İzzettin
