GitHub user hditano created a discussion: Microsoft Graph API - Scopes should
be an empty list or a list of strings Error
### Apache Airflow version
2.10.5
### If "Other Airflow 2 version" selected, which one?
_No response_
### What happened?
While trying to test a small DAG that sends an email and Teams webhook, it
fails to send the email, even though all values (Client ID, Tenant ID, Client
Secret) are correct. I even tested a small Python script to make sure the
values were correct.
Granted User.ReadAll and Mail.Send as per permissions
