James Coder commented on AIRFLOW-4455:
--------------------------------------
/dag_details?dag_id=ParentDag.Subdag
I noticed it on RBAC, but it looked like the logic was the same for classic so
I didn't bother checking.
Error is
UndefinedError: 'None' has no attribute 'timezone'
Which appears to be the result of get_dag returning None
> dag_details broken for subdags

> With the release of 1.10.3 dagbag was removed from the dag_details view. This
> appears to have broken the dag details view for subdags. [line
> 1484|https://github.com/apache/airflow/blob/cec54947d7cf0489284995a6a899b9b94620e301/airflow/models/dag.py#L1484]
> in models/Dag.py now uses the dag fileloc to get the dag, however for a
> subdag, the file loc may not contain the dag if the dag is defined in a
> function as recommended.
