Hi Timothy,
I've followed the ways that is mentioned in above to mirror a github repo wo my source repository in GCP.
However, after initial authentication with github, I select a repository and click on connect repository. I keep seeing an error message "Failed to connect repositories". I read in one of the stackoverflow comments that we need to wait for a couple of days after authenticating for the keys to spread properly. Is it true? I couldn't find any logs in stackdriver as well. The same error pops up for both private and public repos
