INFO: Shutting downNote: Works fine if the async dag was not in deferred state during migration.

How to reproduce
- Start airflow with AF version 2.11.0. (breeze start-airflow --executor CeleryExecutor --backend postgres --use-airflow-version 2.11.0)
- Trigger the below dag
- Migrate to 3.1.0b2 (breeze start-airflow --executor CeleryExecutor --backend postgres)
- Notice the error in triggerer logs
from datetime import datetime
from airflow import DAG
from airflow.utils.dates import days_ago
from airflow.sensors.date_time import DateTimeSensorAsync
with (DAG("async_trigger_sleep", schedule_interval=None, start_date=days_ago(1),tags=["async_migration"])
) as dag:
DateTimeSensorAsync(
task_id="wait_for_start",
target_time=datetime(2028, 12, 10),
)Works fine with the below dag:
from airflow import DAG
from pendulum import today
from airflow.sensors.date_time import DateTimeSensorAsync
with DAG(
"async_trigger_sleep",
schedule=None,
start_date=today("UTC").add(days=-1),
tags=["async_migration"],
) as dag:
DateTimeSensorAsync(
task_id="wait_for_start",
# wait for 1 minute from the DAG execution date
target_time="{{ (execution_date + macros.timedelta(minutes=1)).isoformat() }}",
