Hi, i've added the roles as specified but the error still exists.   
I've also tried to create a normal workspace and that worked.   
After that I created a workspace kind=project with hub-id from the normal workspace and the project hub was created. So the problem only exists with kind=hub.  
Before the above error accoured (Tenant move error) the error below appeared.
