rosdistro cache failing with yaml.scanner.ScannerError: mapping values are not allowed here

edit

I had set permissions on my internal rosdistro restrictively- it required an ssh key to access. My current solution is to make the rosdistro gitlab project 'public' within my lan and this error goes away. I think if I uploaded the right ssh key to gitlab it would work- either /var/lib/jenkins/.ssh/id_rsa.pub, or /root/.ssh/id_rsa, or /home/jenkins-slave/.ssh/id_rsa? All of those map to buildfarm_deployment_config keys, if I figure it out I'll post an answer.
