Just as a follow-up on the solution. This error came from a Git Repository Monitor. The Docker Image for Build Master does not include git installed out of the box. This will require you to either install git on the running container or use a BuildMaster Agent/SSH server to be added and to run this on there. The other issue was that the repository monitor was using a secure resource from a specific application, so the repository monitor needs to specify the application it uses as well.
