There was already a question some months ago but no resolution was found. So I am asking again.
My /me/todo/lists call is failing with a very unuseful 503 server error.
It does not seem to be a permission error because I got a 403 error when I forgot to use the scope Tasks.ReadWrite at first.
It also does not seem to be a throttling issue because I dont't get a "retry-after" header in the response. Also I would expect a 429 error in case of throttling.
It works on Graph Explorer with the same account.
The endpoint /me (To receive account information) works (In my code).
The error response:
"message": "The service is unavailable.",
