It looks like the source is still able to read records event if you’ve have this oauth related error at the end.
I think think the root cause of your problem is another error:

It looks like a date field, used as a cursor field on one of the stream, is None and the connector expects it to be non nullable to perform a date parsing.
Could you please open an issue on our GitHub repo?
