   As a workaround. Using this config and **deleting** the DAG allows it to continue running:
   ```python
   def create_subdag(dag):
       with DAG(dag_id=f"{dag.dag_id}.subdag", start_date=days_ago(0), schedule_interval="@once", catchup=False) as dag:
           DummyOperator(task_id="task")
       return dag
   ```
