tirkarthi opened a new issue, #47706: URL: https://github.com/apache/airflow/issues/47706
### Apache Airflow version main (development) ### If "Other Airflow 2 version" selected, which one? _No response_ ### What happened? `NameError` on task execution completion using LocalExecutor . It looks like `block_orm_access` deletes these attributes from settings module and the registered lambda functions runs after the attributes have been deleted. Probably instead set them to None and run the lambda only when the value is not None like `os.register_at_fork(after_in_child=lambda: engine and engine.dispose(close=False))` https://github.com/apache/airflow/blob/a3435f11bbf2c2c487ec1be53e21ab574f119b61/task-sdk/src/airflow/sdk/execution_time/supervisor.py#L223-L242 ``` [2025-03-13, 06:23:01] ERROR - Exception ignored in: <function configure_orm.<locals>.<lambda> at 0x7f9a6bddb880> chan="stderr" source="task" [2025-03-13, 06:23:01] ERROR - Traceback (most recent call last): chan="stderr" source="task" [2025-03-13, 06:23:01] ERROR - File "/home/karthikeyan/stuff/python/airflow/airflow/settings.py", line 392, in <lambda> chan="stderr" source="task" [2025-03-13, 06:23:01] ERROR - os.register_at_fork(after_in_child=lambda: engine.dispose(close=False)) chan="stderr" source="task" [2025-03-13, 06:23:01] ERROR - ^^^^^^ chan="stderr" source="task" [2025-03-13, 06:23:01] ERROR - NameError: name 'engine' is not defined chan="stderr" source="task" [2025-03-13, 06:23:01] ERROR - Exception ignored in: <function configure_orm.<locals>.<lambda> at 0x7f9a6bddb920> chan="stderr" source="task" [2025-03-13, 06:23:01] ERROR - Traceback (most recent call last): chan="stderr" source="task" [2025-03-13, 06:23:01] ERROR - File "/home/karthikeyan/stuff/python/airflow/airflow/settings.py", line 393, in <lambda> chan="stderr" source="task" [2025-03-13, 06:23:01] ERROR - os.register_at_fork(after_in_child=lambda: async_engine.sync_engine.dispose(close=False)) chan="stderr" source="task" [2025-03-13, 06:23:01] ERROR - ^^^^^^^^^^^^ chan="stderr" source="task" ``` ### What you think should happen instead? _No response_ ### How to reproduce 1. Run `asset_produces_2` dag. 2. Check the `producing_task_2` task instance log. ### Operating System Ubuntu 20.04 ### Versions of Apache Airflow Providers _No response_ ### Deployment Virtualenv installation ### Deployment details _No response_ ### Anything else? _No response_ ### Are you willing to submit PR? - [ ] Yes I am willing to submit a PR! ### Code of Conduct - [x] I agree to follow this project's [Code of Conduct](https://github.com/apache/airflow/blob/main/CODE_OF_CONDUCT.md) -- This is an automated message from the Apache Git Service.
