If you gets an error like this:
deploy dev-branch to master
deploy aborted, operation incomplete. Verify configuration of the remote repository and retry.
org.eclipse.jgit.api.errors.TransportException: email@example.com:org/repo.git: expected report for ref refs/heads/master not received
Check https://www.githubstatus.com/ - the error probably means github is experiencing issues. You can wait until github is back up and then try to deploy/push again :)
