> If the Airflow celery executor receives a bad response from a worker (e.g. unpickled
response), then it will crash the scheduler and cause it to restart.
> We should code defensively around the interactions with celery so that we just log errors
instead of crashing the scheduler.
> It might makes sense to make the try catches one level higher (to catch errors from all
executors), but this needs some investigation.
