Hey Matt,
Yeah there was a typo in my same code, should not have been:
logging.info('Wrote answer, key is: %s', str(answer.key()))
but rather:
logging.info('Wrote answer, key is: %s', str(answer))
What that is telling you is that an answer entity was successfully
written. So, now you know that the entity is getting written, what is
the next logging line? Are you getting an entity back from the
datastore?
