### Apache Airflow version 2.9.0 ### If "Other Airflow 2 version" selected, which one? 2.8.4 ### What happened? Just as MathematicalOwl told in at the end of a stackoverflow post: https://stackoverflow.com/questions/59959290/airflow-sla-miss-callback-function-not-triggering Unlike the on_failure_callback that is looking for a python callable function, it appears that sla_miss_callback needs the full function call. Only below way it can work, then no context except dag_id. ` def on_sla_miss_callback(dag): continue dag_id="my_example_alert" with DAG( dag_id=dag_id, sla_miss_callback=on_sla_miss_callback(dag_id), this_will_skip = BashOperator( task_id="this_will_skip", #bash_command='echo "hello world"; exit 99;', bash_command='echo "hello world"; sleep 40;', #execution_timeout=timedelta(seconds=3), sla=timedelta(seconds=32), dag=dag, ) ` ### What you think should happen instead? _No response_ ### How to reproduce Just as described in "what happended", define a sla_miss_callback, only take dag_id as input, then give the callback to DAG as construction input by sla_miss_callback=sla_miss_callback(dag_id). Add a operator with sla little than the execution duration. Then the callback is triggered. But if define the callback like these, all not working: ` #def on_sla_miss_callback(dag, task_list, blocking_task_list, slas, blocking_tis, *args, **kwargs): #def on_sla_miss_callback(dag, task_list, blocking_task_list, slas, blocking_tis): #def on_sla_miss_callback(*args, **kwargs): def on_sla_miss_callback(dag): ` ### Operating System centos 7 ### Versions of Apache Airflow Providers no providers are used in this example ### Deployment Official Apache Airflow Helm Chart ### Deployment details Both 2.9.0/2.8.4 manual deployment on centos cluster. And also a K8S cluster by official helm and docker image. ### 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.
