Answer 1

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 ?

Answer 2

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.
