Getting 400 Bad Request Error for MSGraph's create subscription api [Error Code - ExtensionError]

问题

Trying to create a subscription to get a channel for msgraph one drive notifications for file creation/upload. I am hitting the URL -

https://graph.microsoft.com/v1.0/subscriptions

with proper headers and the following body -

{ 
    "changeType": "updated",
    "notificationUrl": "https://xxxxx.xxxxxxxxx.com/zzzz/qwertqwert",
    "resource": "/users/{user-id}/drive/root",
    "expirationDateTime": "2017-02-18T19:49:40.000Z",
    "clientState": "justsomerandomstring"

}

I am getting the following response : 400 Bad Request Error

{
  "error": {
    "code": "ExtensionError",
    "message": "Operation: Create; Exception: [Status Code: BadRequest; Reason: Bad Request]",
    "innerError": {
      "request-id": "2862896286-5415-4921-gbn5-8741288985",
      "date": "2017-02-17T17:30:22"
    }
  }
}

I was making the same request 30-32 hrs back. Was getting the subscription-id as well as the file notifications on my redirection servlet. Not able to figure out what changed. Couldn't find any helping documentation either

Got the same error here and it took me a while to find out what is the problem so I share this with you here.

Here's the working code:

$subscription = new Subscription([
  'resource'        => "me/mailFolders('Inbox')/messages?filter=id eq %27" . $draftEmail->getId() . '%27', 
  'notificationUrl' => 'https://my.domain.fr',
  'changeType'      => 'updated',
  'expirationDateTime' => date(DATE_ISO8601, strtotime('+48 hours'))
]);

The line which was wrong for me is:

'resource' => 'me/messages/' . $draftEmail->getParentFolderId(),

And i replace it with

'resource' => "me/mailFolders('Inbox')/messages?filter=id eq %27" . $draftEmail->getId() . '%27',

I found my answer in this link: https://msdn.microsoft.com/en-us/office/office365/api/notify-rest-operations#subscribe-to-changes-in-my-mail-calendar-contacts-or-tasks

But in my opinion the "resource" parameter should be more documented on graph api documentation and the error message return must specify WHY this is a BadRequest.
