ammarchalifah-bolt opened a new issue, #37243:
URL: https://github.com/apache/airflow/issues/37243
### Apache Airflow version
Other Airflow 2 version (please specify below)
### If "Other Airflow 2 version" selected, which one?
2.7.3
### What happened?
I have a use case where I want to pass multiple callbacks as a list to DAG's
`default_args` dictionary. However, this list of callbacks is not supported.
```
Traceback (most recent call last):
File
"/home/airflow/.local/lib/python3.9/site-packages/airflow/models/taskinstance.py",
line 1702, in _run_finished_callback
callback(context)
File
"/home/airflow/.local/lib/python3.9/site-packages/datahub_airflow_plugin/datahub_plugin_v22.py",
line 238, in custom_on_failure_callback
on_failure_callback(context)
TypeError: 'list' object is not callable
```
I thought list of callbacks is supported, could we also support this in
`default_args`?
### What you think should happen instead?

Set a DAG with lists of callbacks passed in `default_args`
