clearTaskInstances REST endpoint on manually triggered dags with logical_date=None

[eflavio]

Hello,

We are on airflow 3.1.3 and mostly trigger our dags via REST API and do not control logical_date (its None).

When trying to clear multiple task instances between start_date and end_date using the API endpoint /api/v2/dags/{dag_id}/clearTaskInstances, we realized that these task instances are not found and therefore not cleared.
I had a look at the source code and airflow is indeed applying start_date and end_date filtering on the logical_date (which is None as described) (https://github.com/apache/airflow/blob/main/airflow-core/src/airflow/serialization/serialized_objects.py#L3397)

Is this a bug? Should the filtering work on a different attribute if logical_date is None? Is the intended use to set the logical_date explicitely?

Thanks in advance!
