    Hi @Kelwen C W QIU

    I am able to replicate the same issue with the above Graph API endpoint.
    As a workaround, to list the worksheets use the below Graph API in sequence:

    GET /me/drive/root/children
    GET /me/drive/items/{id}/workbook/worksheets


    For executing the above endpoint using relative path, I would recommend you to raise a support case with Microsoft Graph, a Support Engineer will be able to assist you better. You can raise support ticket from or

    Hope this helps.

    Hi Kelwen C W QIU please refer to this recent same issue, it seems that this problem may be a temporary server-side problem, please check if it still exists in your environment.
