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

Result:

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
http://aad.portal.azure.com/ or https://admin.microsoft.com/#/support/requests.

Hope this helps.
