Using the same Access Token I was able to access "https://graph.microsoft.com/v1.0/users" but when I tried to use it to get data from a SP List I am getting the error above

Solution

  • It looks like a misconfiguration of your app registration. You have assigned SharePoint API specific permissions, based on your provided screenshot from Microsoft Entra admin center:

    What you actually want are Graph permissions.

    Resolving steps:

    1. Open Microsoft Entra admin center
    2. Navigate to app registrations
    3. Select your app
    4. Select API permissions
    5. Click add a permission
    6. Select Graph API (over here you previously selected Sharepoint)
    7. Select Site.ReadAll

    It should look like this when you´r done:
