@EunSeop how did you set DAG schedule so that it worked? I set up `schedule_interval='@weekly',` cleaned database, and turned on the DAGs: `example_external_task_marker_parent` and `example_external_task_marker_child`. After that my scheduler failed with the error: `AttributeError: 'TaskInstance' object has no attribute 'task'` -- This is an automated message from the Apache Git Service.
