It seems the response of the following OneDrive API has been changed lately.
GET /v1.0/drive/items/{item-id} * item-id: id of "root"
Previous response: The "driveItem" resource does not include "parentReference" property.
Current response: The "driveItem" resource includes "parenetReference" property with only "driveId" attribute.
I couldn`t find this change in the Changelog (https://developer.microsoft.com/en-us/graph/docs/concepts/changelog).
Were there any changes in OneDrive API response lately?
