Unable to import repos

I’m having trouble importing bare git repos in 7.10.4.
I’ve followed the guide and the group is created successfully but it fails to import the project

 * Failed trying to create oldsite (legacyGit/oldsite.git)
   Validation Errors: {:creator=>["can't be blank"], :namespace=>["can't be blank"], :base=>["Can't check your ability to create project"]}

I’ve checked permissions are all correct and am not sure where to go next?
