I’m currently working on webhook notification for SharePoint Online drive using MS Graph API. The subscription is already setup as bellow.

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

{
    "changeType": "updated",
    "notificationUrl": "https://a123bluhbluh.ngrok-free.app/api/WebHook",
    "resource": "/drive/root",
    "expirationDateTime": "2024-07-01T00:00:00Z",
    "clientState": "c9a46c1f-9d7d-4e2b-80d3-4b18a0d0d4ae"
}

Whenever I make any change in the drive by adding/deleting a file I get a notification but the resourceData is null (I only get OdatType).

{"value":[
   {"subscriptionId":"XXX",
      "clientState":"c9a46c1f-9d7d-4e2b-80d3-4b18a0d0d4ae",
      "tenantId":"XXX",
      "resource":"drives/root",
      "resourceData":{
          "@odata.type":"#Microsoft.Graph.DriveItem",
          "Id" : null,
          "ODataEtag" : null,
          "ODataId" : null
       },
      "changeType":"updated",
      "subscriptionExpirationDateTime":"2024-07-01T00:00:00Z"
    }
  ]
}

I also tried adding "includeResourceData": true to my subscription but failed (It seems like includeResourceData is not vaild for sharepoint).

I really need file(item) ID for other function. Everyone Please help me!!
