unauthenticated while trying to get onedrive data via Microsoft Graph

Question

hi everyone,
i am using an office365 family account. Now i am trying to access my files in onedrive via graph api. My first try is using the deviceflow example from Microsoft (device_flow_sample.py). If i am trying to access my accountdata this is working well (endpoint "https://graph.microsoft.com/v1.0/me"). After this i tried to access onedrive (endpoint "https://graph.microsoft.com/v1.0/me/drive"). But then i got an 401 ("unauthenticated") as a response. I though that i am using the wrong authority-url for my account but then i tried it with the graph-explorer (https://developer.microsoft.com/de-de/graph/graph-explorer) and i got the same result.

Is it possible to access onedrive with a office365 family account? I didnt found a good ressource whitch type of Microsoftaccount is able to access which ressource. I would be very thankful if someone can give me a hint.

Hi Shiva,
thanks for your reply. In the meantime i found the solution. It was not a authenticationproblem but a authorizationproblem. My Sessiontoken was correct and the permission in the azureportal too. But in my code i requested to less permission....

Thank you for your trouble.
