When I make a request to this endpoint in the doc then ı get the following error and ı am sure, ı have the necessary "permissions" for the request.

Error and Message:

  • Error: 401 - FileOpenUserUnauthorized
  • Message: You do not have permissions to open this file in the browser.

I did some research and the same problem is mentioned in forums here:

    Same for me, my app runs without problem for years, and this morning got this error. My query is : https://graph.microsoft.com/v1.0/me/drive/items/E97916D0B5077B6C!4981/workbook/worksheets('Documents')/usedRange.

    Not working in MS Graoh Explorer either.

    I guess the problem is on Microsoft side. Any clues ?

    I am running into this for personal OneDrive accounts. I consented Files.ReadWrite but still running into the same issue.

    "https://graph.microsoft.com/v1.0/me/drive/items/<id>/" works to get Excel workbook but "https://graph.microsoft.com/v1.0/me/drive/items/<id>/workbook/worksheets" show following error.

    Any help here would be appreciated. Screenshot 2024-06-04 at 5.08.34 PM
