Allen Lee updated AIRFLOW-6671:
-------------------------------
Description:
I have been trying to get a slack message callback to trigger on SLA misses.
I've noticed that:
# sla_misses get registered succesfully in the Airflow web UI at slamiss/list/
# *on_failure_callback* works succesfully
However, the *sla_miss_callback* function itself will never get triggered.
What I've tried:
* Different combinations adding 'sla' and 'sla_miss_callback' at the
default_args level, the dag level, and the task level
* Checking logs on our scheduler and workers for SLA related messages
[https://github.com/apache/airflow/blob/master/airflow/jobs/scheduler_job.py#L416],
but we haven't seen anything
* The slack message callback function works if called from any other
basic task or function
