> If {{dag.doc_md = __doc__}}, but there are no docstrings on the file, the
> Graph view will error with:
> {code}
> AttributeError: 'NoneType' object has no attribute 'strip'
> {code}
> The UI should just assume we have no docs to show for the DAG. I suspect user
> in AIRFLOW-625 ran into this error.
