I did a bit of research and found that TaskInstance uniqueness is defined by (dag_id, task_id, run_id, map_index) (see https://github.com/apache/airflow/blob/f4f48b9abfb17450f66f68beb5170d0faf6d0571/airflow-core/src/airflow/models/taskinstance.py#L590-L592) The fact that `get_task_instance` doesn't include `dag_id` appears to violate this invariant. This can lead to multiple rows being returned when multiple DAGs share the same `task_id` and `run_id`. I'm going to fix this and add a regression test to cover this case (TI uniqueness). -- This is an automated message from the Apache Git Service.
