I'm also facing this problem sometime while using basic python task with
`mutiple_outputs` and have `None` value in return.
I noticed the error log is similar to this issue, maybe we can have a look
on null value checking in xcom push process.
``` python
INFO - Done. Returned value was: {'df': None, 'tasks': []}
ERROR - Task failed with exception: source="task"
AirflowRuntimeError: API_SERVER_ERROR: {'status_code': 422, 'message':
'Remote server returned validation error', 'detail': {'detail': [{'type':
'missing', 'loc': ['body'], 'msg': 'Field required', 'input': None}]}}
