It did not occur when using PostgreSQL as a DB(sql_alchemy_conn, result_backend). It seems to occur only in MySQL.

Is this resolved? I am still seeing the same issue

what is the default_timezone in your airflow.cfg? The default value is default_timezone = utc and if you changed this to other timezone like Asia/Shanghai, then backfill/test seems not working.
