TriggerDagRunOperator.execute cannot be called outside of the Task Runner!

### Apache Airflow version Other Airflow 2 version (please specify below) ### If "Other Airflow 2 version" selected, which one? 3.0.6 ### What happened? The TriggerDagRunOperator can not be executed from a task anymore ### What you think should happen instead? Either it should work like in Airflow 2.11 or there should be some documentation how to migrate existing DAGs ### How to reproduce I have added an example with two minimal Dags that reproduce the problem [x_task_run_demo.py](https://github.com/user-attachments/files/22595855/x_task_run_demo.py) ```python import datetime import logging import pendulum import pytz from airflow import DAG from airflow.sdk import task, Param from airflow.providers.standard.operators.trigger_dagrun import TriggerDagRunOperator # This DAG should schedule the other one multiple times with DAG( dag_id = "Task-Run-Demo" , schedule = "0 0 * * *" # Daily at midnight (00:00) , catchup = False , params = { "schedule_date" : Param(f"{datetime.date.today()}", type="string", format="date") } ) as dag: @task def schedule_dags(**kwargs): for i in range(5): execution_date = datetime.datetime.utcnow() + datetime.timedelta(minutes = 5) logging.info(f"Trigger report for counter #{i} at '{execution_date}'") try: TriggerDagRunOperator( task_id = f"create_reports_dag_{i}" , trigger_dag_id = "Create-Reports" , conf = { "counter": i } , logical_date = execution_date.replace(tzinfo = pytz.UTC), ).execute(context = kwargs) except Exception as ex: error_message = str(ex) logging.error(f"Failed to trigger DAG #{i}: {error_message}") schedule_dags() # This DAG should not be executed directly but triggered by the Task-Run-Demo DAG with DAG( dag_id …
