opeida opened a new issue, #51816:
URL: https://github.com/apache/airflow/issues/51816
### Apache Airflow version
3.0.2
### If "Other Airflow 2 version" selected, which one?
_No response_
### What happened?
The exception occurred when the DAG ran with `dag.test()` attempted to
retrieve a variable from the API server. Some similar issues have been opened
(#48554, #51062, #51316), but the pull requests provided as the solutions
(#50300, #50419) were included in 3.0.2 and did not fix the problem.
```
Exception has occurred: ImportError
cannot import name 'SUPERVISOR_COMMS' from
'airflow.sdk.execution_time.task_runner'
(/workspaces/airflow/.venv/lib/python3.12/site-packages/airflow/sdk/execution_time/task_runner.py)
File "/workspaces/airflow/test.py", line 7, in <module>
x = Variable.get("my_variable")
^^^^^^^^^^^^^^^^^^^^^^^^
ImportError: cannot import name 'SUPERVISOR_COMMS' from
'airflow.sdk.execution_time.task_runner'
(/workspaces/airflow/.venv/lib/python3.12/site-packages/airflow/sdk/execution_time/task_runner.py)
```
### What you think should happen instead?
The variable should have been successfully retrieved without exceptions.
### How to reproduce
1. Set the variable: `airflow variables set my_variable my_value`
2. Run DAG:
```
import logging
from airflow import DAG
from airflow.providers.standard.operators.empty import EmptyOperator
from airflow.providers.standard.operators.python import PythonOperator
from airflow.sdk import Variable
x = Variable.get("my_variable")
def my_function(my_var: str) -> None:
logging.getLogger(__name__).info(my_var)
with DAG("test_dag") as dag:
start = EmptyOperator(task_id="start")
py_func = PythonOperator(
task_id="py_func",
python_callable=my_function,
op_kwargs={
"my_var": x
}
)
end = EmptyOperator(task_id="end")
start >> py_func >> end
if __name__ == "__main__":
dag.test()
```
### Operating System
Debian GNU/Linux 12 (bookworm)
### Versions of Apache Airflow Providers
_No response_
### Deployment
Other Docker-based deployment
### Deployment details
Extended image based on `apache/airflow:slim-3.0.2-python3.12`
