Date Wed, 07 Jun 2017 18:41:18 GMT
Dan Davydov created AIRFLOW-1288:
------------------------------------

             Summary: Bad owners field in DAGs breaks Airflow front page
                 Key: AIRFLOW-1288
                 URL: https://issues.apache.org/jira/browse/AIRFLOW-1288
             Project: Apache Airflow
          Issue Type: Bug
          Components: webserver
            Reporter: Dan Davydov


DAGs that have owners set to a bad value break the front page of the webserver with an error
like below. Instead these should just cause import errors for the specific dags in question.
