   ### What happened?
   
   I have 2 DAG in different files.
   
   Parent 
   ```
   with DAG(
       dag_id="parent_dag_id",
       default_args=default_args,
       description="PARENT DAG",
       start_date=datetime(2025, 1, 1),
       schedule_interval="@hourly",
       catchup=False,
   ) as dag:
       trigger_child = TriggerDagRunOperator(
           task_id="trigger_child",
           trigger_dag_id="child_dag_id",
           reset_dag_run=True,
           wait_for_completion=True,
       )
   
     trigger_child
   ```
   
   Child
   ```
   def call_func():
     print("Hello")
   
   with DAG(
       dag_id="child_dag_id",
       default_args=default_args,
       description="CHILD DAG",
       start_date=datetime(2025, 1, 1),
       catchup=False,
   ) as dag:
     task = PythonOperator(
           task_id="call_function",
           python_callable=call_func,
       )
     
     task
   ```
   
   Everytime I trigger parent_dag, it will trigger the child_dag also, but the 
child_dag will stuck in queue
