Planner - BadRequest when updating Task Details

Question

When using the Graph API I can successfully create a task, I then wish to update the task details, specifically the description and to add some references.

I'm following the documentation here https://graph.microsoft.io/en-us/docs/api-reference/beta/api/taskdetails_update

I add the request headers, Authentication Bearer, If-Match using the eTag from when I created the task. The URL is:

https://graph.microsoft.com/beta/tasks/6oqAlz30WE66F915zUcSepYAM2ki/details

Http method used is PATCH Body is:

{
  "description": "My Task Title description",
  "references": {
    "https://tenant.sharepoint.com/teams/teamsite/_layouts/15/WopiFrame.aspx?sourcedoc={521F1D0F-397D-4163-BB16-7C9EF436650B}&file=Release Notes.one&action=view&DefaultItemOpen=1": {
      "alias": "OneNote",
      "type": "OneNote"
    }
  }
}

Http response is:

StatusCode: 400, ReasonPhrase: 'Bad Request'

Response Content is:

{
    "error": {
        "code": "",
        "message": "The request is invalid.",
        "innerError": {
            "request-id": "4e2eae7d-9587-4a69-8c9d-40c5d571190a",
            "date": "2016-06-24T10:57:33"
        }
    }
}

Any ideas as to what I may be doing wrong here?

Tried removing the "references" object from the request, so just updating description and that works, so it must be something about the references that it doesn't like — Terry Hagan
Okay, sorted this out. The URL value in references must be encoded. That's it. — Terry Hagan

The URL in the references object needs to be encoded, that's it. i.e.

{
  "description": "My Task Title description",
  "references": {
    "https%3A%2F%2Ftenant.sharepoint.com%2Fteams%2Fteamsite%2F_layouts%2F15%2FWopiFrame.aspx%3Fsourcedoc%3D%7B521F1D0F-397D-4163-BB16-7C9EF436650B%7D%26file%3DRelease+Notes.one%26action%3Dview%26DefaultItemOpen%3D1": {
      "alias": "OneNote",
      "type": "OneNote"
    }
  }
}
