Unexpected "Access Denied" from Graph API list-children request

Question

Our client has a personal OneDrive account with a folder called "Arq Backup Data" in it. The account is currently over quota.

This request:

GET https://graph.microsoft.com/v1.0%2Fme%2Fdrive%2Froot%3A%2FArq%20Backup%20Data%3A%2Fchildren?top=1000

returns "Access Denied" for some reason. We can't figure out why. The full JSON response is:

{"error":{"code":"accessDenied","message":"Access Denied","localizedMessage":"This item might have been deleted, expired, or you might not have permission to access it. Contact the owner of this item for more information.","innerError":{"date":"2024-06-26T14:30:54","request-id":"c304db39-2da5-4647-bff5-d68586fb748f","client-request-id":"ee99e8f6-248a-42cd-84bf-994d71af3dc3"}}}

I understand it's not possible to create or edit files when over quota, but why are we getting "access denied" for listing children of a folder?

Hi @Arq Support

Does the logged in user have Files.Read.All permission? Try logging in to Graph Explorer with your personal account and calling the endpoint again.

Hope this helps.
