Thought I'd share this issue to see if any of you are also having this problem. I work on a fairly low traffic site but have been intermittently getting random 500 errors from our Google cloud functions, with no logs at all. We spent a couple of afternoons trying to refactor / debug our code with hopes that it would solve this issue. We stumbled upon this recent github issue, a bit late. This feels like something we should have gotten a heads up about. https://github.com/firebase/firebase-functions/issues/816
