Triggerer can not access Variables #61676
Description
Apache Airflow version
3.1.7
If "Other Airflow 3 version" selected, which one?
No response
What happened?
I can not access variables inside the triggerer by using the airflow.sdk.Variable module, an error VARIABLE_NOT_FOUND is raised.
What you think should happen instead?
Worker can access Variable module however Triggerer can not.
How to reproduce
1.- Create a new variable with name retries and a value of 10.
2.- Put the attached files in the right folders:
- dag_example.py into your dag folder
- lib_example.py into a folder in yout PYTHONPATH
Run the DAG:
- The first task access the variable correctly
- The second task (the one deferred) fails because the triggerer can not access the variable.
You get an error like this:
[2026-02-09T15:22:57.644686Z] ERROR - Trigger ejemplo_deferrable_3_0/manual__2026-02-09T15:21:16.609292+00:00/async_task/-1/2 (ID 17) exited with error VARIABLE_NOT_FOUND: {'message': 'Variable retries not found'}AirflowRuntimeError: VARIABLE_NOT_FOUND: {'message': 'Variable retries not found'}
