I have this too now. No fundamental changes to my files and suddenly this happens. I tried all the above suggestions, but no joy. I’ve also reverted to previous commits that I know worked - again I still see this error. Just to be thorough, I even cloned my last known working version and reinstalled all node modules. But again, I still see this problem. Curiously, my deployed production version is still running and I can rebuild that on the production server. I now super scared to push any updates in case that breaks too. What on earth is going on? How can this possibly happen without any changes made???
