Issues with TeamCity 9.1.X

[DVGeoffrey]

Not seeing webhooks since a few days after our TeamCity upgrade (not sure why it didn't stop working right away). Errors I'm finding in the logs:

We're running TeamCity Enterprise 9.1.5 (build 37377).

D'oh! This is the same issue as last time (#1). I removed the dummy GIT repo I put in, forgetting its needed as a workaround. Added it back and it's working.

I just downloaded and installed the webhooks TeamCity addin and I'm having the same issue. I thought it would have been fixed by now?
How did you create the dummy Git repo? Do you actually have a Git repo or is there a way to fool TeamCity to accept a nonsense uri?

[DVGeoffrey]

I created an actual Git repo which TeamCity could access. Had to make sure it was the first repo in the list too. Needed to delete an SVN repo from the buildType, add the Git repo and then add the SVN repo back.
