Content export fails with error Validation failed: Label has already been taken when using a non-admin user

Issue

• An attempt to export a repository or a content-view version or the entire library environment, using a non-admin user, one of the following errors occurs:

  # hammer content-export complete repository --name TestR --product TestP --organization-id 1
  Could not export the repository:
   Validation failed: Label has already been taken, Name has already been taken   
  
  # hammer content-export complete library --format syncable --organization-id 1 
  Could not export the library:
   422 Unprocessable Entity
  

  • The same problem can be reproduced using the REST API endpoint or the Red Hat Satellite Ansible Collection for content export.

  • The non-admin user in question has the Content Exporter role assigned to it.
