I manually implemented the MS Teams notification in AWS MWAA using the repo code. But I wonder if there is a way to configure the connection using Terraform. The terraform documentation doesn't mention anything related to connections.

File "/usr/local/lib/python3.11/site-packages/airflow/models/taskinstance.py", line 1702, in _run_finished_callback
callback(context)
File "/usr/local/airflow/include/ms_teams_callback_functions.py", line 55, in success_callback
teams_notification = MSTeamsWebhookOperator(
^^^^^^^^^^^^^^^^^^^^^^^
File "/usr/local/lib/python3.11/site-packages/airflow/models/baseoperator.py", line 437, in apply_defaults
result = func(self, **kwargs, default_args=default_args)
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
File "/usr/local/airflow/include/operators/ms_teams_webhook_operator.py", line 74, in init
self.hook = None
^^^^^^^^^
File "/usr/local/lib/python3.11/site-packages/airflow/models/baseoperator.py", line 1045, in setattr
super().setattr(key, value)

After upgrading to Airflow 2.5.1 recently the ms_teams_webhook_hook.py won't function anymore as intended. The error was in the summary and in the activityTitle overhanded to the webhook here. It was related to the quotation marks used in self.message. Double Quotes are used there and they seem to create a malformed payload.
Replacing them with single quotes won't work either and also creates a malformed payload.

My best Idea to fix it was to

self.message = message

here with

self.message = message.replace('"', '\\"')

The Problem with this workaround is that the Message won't be formatted ideally anymore.

I'm open to better Ideas or to create a PR if guided what the best way to create one would be.
