choo121600 opened a new pull request, #67250:
URL: https://github.com/apache/airflow/pull/67250
When a backfill is requested with from_date after to_date, the Backfill
record was committed before _get_info_list() returned an empty list, leaving an
orphaned record that blocked subsequent backfills with AlreadyRunningBackfill
until the scheduler's 2-minute cleanup ran.
Add an InvalidBackfillDateRange exception and validate from_date <= to_date
at the top of _validate_backfill_params(), before any DB operations.
(cherry picked from commit 153623856efb44a3f60ef9fdb67e22e05609e067)
