We are trying to make GET request on this API endpoint: GET https://graph.microsoft.com/v1.0/communications/calls/7531d31f-d10d-44de-802f-c569dbca451c/participants
But, we are getting 500 Internal Server Error - UnknownError.
We already have a registered application (clinet id: b6c6076c-d3c3-43b4-969f-77f7a4675af8 , App name: SPACE @ SSST, App Owner: exxx.agic@sxxt.edu.xx) with required permissions and we successfully send the requests to other API endpoints.
Can you tell us why we get this error?
