External integrations still emit the Airflow 2 tree URL, which otherwise becomes a dead link in Airflow 3. Redirect that legacy URL to the current Dag overview so existing DataHub links remain usable. Co-authored-by: Copilot <[email protected]>

The issues this connects to was marked as "not planned". We got rid of tree view so long ago. This seems like a bug acryl-datahub-airflow-plugin should fix. Not a one-off workaround in core airflow. Because tons of links to old airflow versions would also be broken. |

Airflow 3 no longer serves the Airflow 2
/tree?dag_id=...URL, but external integrations such as DataHub still generate it. Those links currently end in a 404.Add a compatibility route that redirects legacy tree links to the current Dag overview, preserving existing integration links while users migrate to the new URL format. The redirect also handles malformed links without a Dag ID by sending them to the Dag list.
