UnknownError issue with when querying communications/calls/{id}

Question

I am using the following code to query the Graph API to retrieve a Team's call information. However, I constantly get the error (pasted below). I am not sure what I am missing. Any help is much appreciated.

Code:

// The client credentials flow requires that you request the  
// /.default scope, and preconfigure your permissions on the  
// app registration in Azure. An administrator must grant consent  
// to those permissions beforehand.  
string[] scopes = new[] { "https://graph.microsoft.com/.default" };  
  
// Multi-tenant apps can use "common",  
// single-tenant apps must use the tenant ID from the Azure portal  
//string tenantId = "common";  
string tenantId = AzureDetails.TenantID;  
  
// Values from app registration  
string clientId = AzureDetails.ClientID;  
string clientSecret = AzureDetails.ClientSecret;  
  
// using Azure.Identity;  
TokenCredentialOptions options = new()  
{  
    AuthorityHost = AzureAuthorityHosts.AzurePublicCloud  
};  
  
// https://learn.microsoft.com/dotnet/api/azure.identity.clientsecretcredential  
ClientSecretCredential clientSecretCredential = new(tenantId, clientId, clientSecret, options);  
  
GraphServiceClient graphClient = new(clientSecretCredential, scopes);  
  
call = await graphClient.Communications.Calls[id].Request().GetAsync();  

Exception:

Code: UnknownError

Hi @Puneeth Umesh Bharadwaj

Try my code:

using Azure.Identity;  
using Microsoft.Graph;  
using Newtonsoft.Json;  
  
  
var scopes = new[] { "https://graph.microsoft.com/.default" };  
  
// Multi-tenant apps can use "common",  
// single-tenant apps must use the tenant ID from the Azure portal  
var tenantId = "{tenant id}";  
  
// Values from app registration  
var clientId = "{client id}";  
var clientSecret = "{client secret}";  
  
// using Azure.Identity;  
var options = new TokenCredentialOptions  
{  
    AuthorityHost = AzureAuthorityHosts.AzurePublicCloud  
};  
  
// https://learn.microsoft.com/dotnet/api/azure.identity.clientsecretcredential  
var clientSecretCredential = new ClientSecretCredential(  
    tenantId, clientId, clientSecret, options);  
  
var graphClient = new GraphServiceClient(clientSecretCredential, scopes);  
  
var devices = await graphClient.Devices  
    .Request()  
    .GetAsync();  
  
var call = await graphClient.Communications.Calls["{call-id}"]  
    .Request()  
    .GetAsync();  
  
Console.WriteLine("call:" + JsonConvert.SerializeObject(call));  

Also, don't forget to replace all variables in "{}" with real values.
