   A workaround for this, for now, is to pass a session to `get_dagrun` method:
   
   ```
   from airflow.settings import Session
   
   session = Session()
   
   def task_instance_mutation_hook(task_instance):
       dag_run = task_instance.get_dagrun(session=session)
       conf = dag_run.conf
   ```
