obarisk opened a new issue, #41563: URL: https://github.com/apache/airflow/issues/41563
### Apache Airflow version 2.10.0rc1 ### If "Other Airflow 2 version" selected, which one? _No response_ ### What happened? _run_finished_callback now logs ``` callback.__name__ ``` however, a simple function callback without .__name__ attribute. BaseNotifier without .__name__ attribute either. It can be a bug if "funcation" or "BaseNotifer" allowed in on_success_callback or on_failure_callback of a dag Or it just missing of documentation or incorrect documentation of [callback](https://airflow.apache.org/docs/apache-airflow/stable/administration-and-deployment/logging-monitoring/callbacks.html) ### What you think should happen instead? if we allow function/Notifer as callback, then we must make function/Notfier callback execute correctly. i.e., modify the log of `callback.__name__`. if we believe callbacks must with ".__name__" attributes, documents required. ### How to reproduce the example dag will fail with airflow=2.10.0 ```python import datetime import pendulum from airflow import DAG from airflow.operators.empty import EmptyOperator def task_failure_alert(context): print(f"Task has failed, task_instance_key_str: {context['task_instance_key_str']}") def dag_success_alert(context): print(f"DAG has succeeded, run_id: {context['run_id']}") with DAG( dag_id="example_callback", schedule=None, start_date=pendulum.datetime(2021, 1, 1, tz="UTC"), dagrun_timeout=datetime.timedelta(minutes=60), catchup=False, on_success_callback=None, on_failure_callback=task_failure_alert, tags=["example"], ): task1 = EmptyOperator(task_id="task1") task2 = EmptyOperator(task_id="task2") task3 = EmptyOperator(task_id="task3", on_success_callback=[dag_success_alert]) task1 >> task2 >> task3 ``` ### Operating System Debian GNU/Linux 12 ### Versions of Apache Airflow Providers apache-airflow-providers-discord | 3.7.1 apache-airflow-providers-slack | 8.8.0 ### Deployment Other Docker-based deployment ### Deployment details _No response_ ### Anything else? _No response_ ### Are you willing to submit PR? - [X] 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.
