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.
Additional information:
It works on Graph Explorer with the same account.
The endpoint /me (To receive account information) works (In my code).
The error response:
{
"error": {
"code": "UnknownError",
"message": "The service is unavailable.",
"innerError": {
"date": "2021-03-31T14:53:42",
"request-id": "b47b308e-c0b3-444d-8392-2c5979e9c48f",
"client-request-id": "b47b308e-c0b3-444d-8392-2c5979e9c48f"
}
}
}
