Failed to query permissions

Issue

When you attempt to open the Sintel Apps page you receive an error “Failed to query permissions”.

Resolution

The error is generally caused by Sintel Apps not having the permissions it requires. There are 3 places to check to overcome this issue.

As a tenant admin please verify the following:

Step 1 – Ensure it’s deployed

Verify the app is deployed from the tenant app catalog by opening
https://YourTenant-admin.sharepoint.com/_layouts/15/tenantAppCatalog.aspx
Switch to classic experience, select Sintel Apps app and from the Files tab menu click Deploy if it’s available (you don’t need to add it to all sites).

Step 2 – Ensure it’s approved

Ensure there is an entry in the API access:
https://YourTenant-admin.sharepoint.com/_layouts/15/online/AdminHome.aspx#/webApiPermissionManagement

If an entry does exist, make sure it’s approved.

Step 3 – Ensure it’s got permissions

Ensure the app has the permissions it needs in Azure.
