      Cause (maybe)

      I've looked to the written projectId=43 and repositoryId=23 and see that the project is a personal repository from a user which was deleted from our Active Directory.

      So it looks like the error comes from the deleted user and the still existing repository.

      Workaround

      Move or delete the repository and the error message is fixed.
