  • Response  404

  • Returned if the project does not exist or the client does not have sufficient permissions to see it.

    Required permission: view project

    Note: A client without sufficient permissions shall not be able to test for the existence of a project. That’s why a 404 is returned here, even if a 403 might be more appropriate.
