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?
For security purpose, I have covered the information of App owner. Thanks for your understanding.
Due to lack of authentication, I cannot see the real content of your link but as below:

HI @Tahir Atovic ,
Could you please let us know whether you have applied below application permissions.
Calls.JoinGroupCallsasGuest.All, Calls.JoinGroupCalls.All, Calls.Initiate.All, Calls.InitiateGroupCalls.All
Well,
I've found this permissions to be added but couldn't find where to apply these.
I'm using graph explorer to test the command and I apply permissions as I go.
Also, I assigned all possible administrator roles using Azure AD admin center and still no go.
Any advice
Thanks
