> UI should not print traceback for missing dag/task in URL
> ---------------------------------------------------------

> Key: AIRFLOW-417
> URL: https://issues.apache.org/jira/browse/AIRFLOW-417
> Project: Apache Airflow
> Issue Type: Bug
> Components: webserver
> Reporter: Dan Davydov
> Assignee: Vijay Bhat
> Priority: Major
> Labels: UI, easy-fix

> that don't exist they get confusing tracebacks rather than an error rendered
> in html like "the dag/task doesn't exist". One such traceback can be seen by
> going to the tree view for any DAG in the UI and then changing the url in the
> address bar for the dag_id to be a non-existent dag. The following traceback
> can be seen:
