console.log on Firebase Cloud Functions simply not logging.
Ok, the problem ended up being that the function wasn't deploying properly.
What had happened was due to some typescript/firebase config issue - the new code was being compiled to a location that wasn't what firebase was looking for.
When deployed the code - some old compiled code was still there to be deployed.
The moral of the story here is: make sure you delete your dist/build/lib directory before deploying - as that will cause an error if firebase is looking in the wrong place.
In case someone wastes as much time as I did. It turned out I was logged into the wrong firebase project ð¤¦ð»♂️.
firebase projects:list
