Good call on the ingore_missing_imports. I just moved that from the [mypy] section into a [mypy-pyspark.*] and found 4 errors that I didn't notice before. The first result in Google for this error points here https://github.com/python/mypy/issues/3905 https://github.com/python/mypy/issues/3905 which explains the issue. I'm ashamed to say I probably just read the first reply, added it to my config and carried on with my day without actually reading what it did.
