503 errors trying to get ToDo lists

Question

When I try to get my ToDo lists, using this endpoint, https://graph.microsoft.com/v1.0/me/todo/lists, I get a 503 error

{
"error": {
"code": "UnknownError",
"message": "The service is unavailable.",
"innerError": {
"date": "2020-11-03T22:16:08",
"request-id": "046d52f9-304a-4f73-884e-e0fa737a92fa",
"client-request-id": "7f73ad15-7558-6a4c-0c64-0761fbb618ba"
}
}
}

I've confirmed that I've given permissions to read this resource.

I am encountering the same issue on my end. I have an office365 linked to my account.

Answer 2

I've already set the right permissions (as far as I know). This is what I'm seeing:

Answer 3

Looking at the request-id on the backend. Your user token did not have the correct permissions. You only had user.read.

To call teh /todo endpoint as per the docs, you'll need to consent to Tasks.ReadWrite. https://learn.microsoft.com/en-us/graph/api/todo-list-lists?view=graph-rest-1.0

If you're doing this just in Graph Explorer, there is a Modify Permissions tab where you can consent this permission.

Answer 4

I cannot repro this with 3 diff Microsoft Accounts (Consumer / MSA). I'm going to escalate this internally.

Answer 5

I have the same error. I have Tasks.ReadWrite permissions setup.
