When clicking "Trigger new build" nothing happens


I hope this is the correct place to ask. As the title says when I click trigger new build, nothing happens, not even an error message. I also see nothing on launchpad.net/builders, so something stops it from getting there. This is the snap in question: https://github.com/GeorgScheumann/argentumagesnap. The repo is already linked and it works on my local machine. So I guess I did some error that stops the build server from doing anything.

I already tried renaming to json and back to yaml as mentioned here: "Build with Github" => can't trigger new build, but that didn’t help. Would be grateful for any suggestions.

You can see the build history for your snap here, it’s failing due to some malformed syntax


Many thanks, I didn’t realize I had a character there, should’ve definitely checked that.
