We're trying to deploy firebase functions and we continuously have this error: The service has encountered an error during container import. Please try again late

As per this doc, it may be due to non-utf8 characters, but there are none (checked using https://stackoverflow.com/a/41741313 grep -axv '.*' ./lib/**/*.js)
It failed 3 times in a row and continues failing. And every time it fails on the same functions.
There is always only one deployment ongoing - we don't run multiple firebase functions deploy at the same time.
The original discussion is on their github, but we were refered here.
