   Did you run `airflow db upgrade` before upgrading to 2.0.0?
   
   https://github.com/apache/airflow/blob/8a4bd3c73eb46c5ddd9312c71772a423fb1fd688/airflow/models/dagbag.py#L183-L188

   I am not sure how `get_last_updated_datetime` can be none, for it to be `None`, you might need to have DAGs in DagBag for Webserver/Scheduler and no records for that DAG in serialized_dag table which does not seem to be easily possible.
   
   Is your Webserver and Scheduler both using 2.0.0 image?
