Direct database access via the ORM is not allowed in Airflow 3.0

[Leon-Sander]

The following error seems to be produced by the function

from airflow.models import DagRun
DagRun.find(dag_id=dag_id)

Traceback (most recent call last):
  File "/home/airflow/.local/lib/python3.12/site-packages/airflow/utils/session.py", line 41, in create_session
    session = Session()
              ^^^^^^^^^
  File "/home/airflow/.local/lib/python3.12/site-packages/airflow/sdk/execution_time/supervisor.py", line 258, in __init__
    raise RuntimeError("Direct database access via the ORM is not allowed in Airflow 3.0")
RuntimeError: Direct database access via the ORM is not allowed in Airflow 3.0

How else do I need to call this to not get the error?

Not being able to access DB is a feature of Airflow 3. For a long time DB has not been part of the public interface of Airflow - and Airflow 3 finally cut the access.

You can use REST API an Python client instead if you want to access information from Aiflow Metadata DB.
