Answer 1

• Try repro the issue outside of your code, by making the same call in Microsoft Graph explorer and the above user
• See whether you provided the necessary permissions for the user
• Validate the token using https://jwt.ms and see it contains scopes/permissions rightly set for the user or not.

I see that you're trying to create new tasks in TODO workload using Application permission. Correct me if i am wrong. Please note that application permission is not supported for creating new tasks in TODO workload.
