Graph API site permissions returning empty list

Question

We created a new site and shared with some users, which added to the site's Members and Visitors sharepoint groups. However, when we query the sites permissions, we receive an empty array, with the right application permission (Sites.FullControl.All). https://learn.microsoft.com/en-us/graph/api/site-list-permissions?view=graph-rest-1.0&tabs=http

Endpoint hit: https://graph.microsoft.com/v1.0/sites/{site_id}/permissions

What exactly is the site permissions endpoint expected to return?

Hi @Rick Huang ,

I tried to replicate this scenario but it is working as expected. To replicate this scenario I have created site permission using Create permission Graph API.

After creating permission successfully, I was able to list permission in the response using this
GET /sites/{sitesId}/permissions Graph API.

Please Note : Site permission resource will not return 'site's Members and Visitors sharepoint groups'. It will return permissions granted to the Azure Apps which you can create as shown above.
It does not return anything related to the good-old classic SharePoint permissions.

For more details about Sites Permission please refer to this documentation.

Hope this helps.
