Opened link of this kind [http://airflow.grinder.uaprom/admin/airflow/tree?dag_id=xxxxxxx]
Version is 1.10.0 (Latest release from here [https://pypi.org/project/apache-airflow/#history)]
I came across this use-case when people open URLs saved few months ago (Actually we updated Airflow, some DAGS were removed)
P.S. My stacktrace looks like this
{code:java}
