URL: https://github.com/apache/airflow/issues/57194
### Apache Airflow version
3.1.0
### If "Other Airflow 2/3 version" selected, which one?
_No response_
### What happened?
**my first dag**
from airflow import DAG
from airflow.providers.standard.operators.python import PythonOperator
from airflow.providers.standard.operators.trigger_dagrun import
TriggerDagRunOperator
from datetime import datetime
def fetch_job():
job_id = 123
target_id = 987
conf = {"job_id": job_id, "target_id": target_id}
print(f"[DAG A] Prepared conf to pass: {conf}")
return conf # pushed to XCom automatically
def trigger_dag_b_callable(**kwargs):
ti = kwargs['ti']
conf = ti.xcom_pull(task_ids='fetch_job') # this is a dict
print(f"[DAG A] Triggering DAG B with conf: {conf}")
TriggerDagRunOperator(
task_id="trigger_dag_b_inner",
trigger_dag_id="dag_b",
conf=conf,
wait_for_completion=False
).execute(context=kwargs)
with DAG(
dag_id="dag_a",
start_date=datetime(2025, 1, 1),
schedule=None,
catchup=False
) as dag:
fetch_job_task = PythonOperator(
task_id="fetch_job",
python_callable=fetch_job
)
trigger_dag_b_task = PythonOperator(
task_id="trigger_dag_b",
python_callable=trigger_dag_b_callable
)
fetch_job_task >> trigger_dag_b_task
the logs of this is fine see them

/>
**my second dag**
from airflow import DAG
from airflow.providers.standard.operators.python import PythonOperator
from datetime import datetime
def process_target(**kwargs):
dag_run = kwargs.get('dag_run')
conf = dag_run.conf if dag_run else {}
print(f"[DAG B] Received conf: {conf}")
job_id = conf.get("job_id")
target_id = conf.get("target_id")
print(f"[DAG B] Processing job_id={job_id}, target_id={target_id}")
with DAG(
dag_id="dag_b",
start_date=datetime(2025, 1, 1),
schedule=None,
catchup=False
) as dag:
process_task = PythonOperator(
task_id="process_target",
python_callable=process_target )
It should get data from one dag but its showing **none**
see the logs

### What you think should happen instead?
_No response_
### How to reproduce
save this file and trigger it
`from airflow import DAG
from airflow.providers.standard.operators.python import PythonOperator
from airflow.providers.standard.operators.trigger_dagrun import
TriggerDagRunOperator
from datetime import datetime
def fetch_job():
job_id = 123
target_id = 987
conf = {"job_id": job_id, "target_id": target_id}
print(f"[DAG A] Prepared conf to pass: {conf}")
return conf # pushed to XCom automatically
def trigger_dag_b_callable(**kwargs):
ti = kwargs['ti']
conf = ti.xcom_pull(task_ids='fetch_job') # this is a dict
print(f"[DAG A] Triggering DAG B with conf: {conf}")
TriggerDagRunOperator(
task_id="trigger_dag_b_inner",
trigger_dag_id="dag_b",
conf=conf,
wait_for_completion=False
).execute(context=kwargs)
with DAG(
dag_id="dag_a",
start_date=datetime(2025, 1, 1),
schedule=None,
catchup=False
) as dag:
fetch_job_task = PythonOperator(
task_id="fetch_job",
python_callable=fetch_job
)
trigger_dag_b_task = PythonOperator(
task_id="trigger_dag_b",
python_callable=trigger_dag_b_callable
)
fetch_job_task >> trigger_dag_b_task
`
then run this
`from airflow import DAG
from airflow.providers.standard.operators.python import PythonOperator
from datetime import datetime
def process_target(**kwargs):
dag_run = kwargs.get('dag_run')
conf = dag_run.conf if dag_run else {}
print(f"[DAG B] Received conf: {conf}")
job_id = conf.get("job_id")
target_id = conf.get("target_id")
print(f"[DAG B] Processing job_id={job_id}, target_id={target_id}")
with DAG(
dag_id="dag_b",
start_date=datetime(2025, 1, 1),
schedule=None,
catchup=False
) as dag:
process_task = PythonOperator(
task_id="process_target",
python_callable=process_target )
