Get current user more information

I am using .NET Core with C# application and there I have integrated the Azure AD authentication. It means any Azure AD user can be logged in to this application. Now at someplace, I want to display the City, State, Country and some other fields value of current logged in user. For that, I have used Microsoft Graph API, but I am not able to get the details successfully. I got an error Request_ResourceNotFound. I used below C# code to get the data for current Logged in user.

var clientId = "<CLIENT_ID>"; // I have used my application client id here
var secret = "<CLIENT_SECRET>"; // I have used my client secret here
var domain = "<DOMAIN>"; // I have used domain here
var credentials = new ClientCredential(clientId, secret);
var authContext = new AuthenticationContext($"https://login.microsoftonline.com/{domain}/");
var token = await authContext.AcquireTokenAsync("https://graph.microsoft.com/", credentials);

var graphServiceClient = new GraphServiceClient(new DelegateAuthenticationProvider((requestMessage) =>
{
    requestMessage
        .Headers
        .Authorization = new AuthenticationHeaderValue("bearer", token.AccessToken);

    return Task.CompletedTask;
}));

var user = await graphServiceClient
    .Me
    .Request()
    .GetAsync(); // Error at this line

But it throws an below error when I used graphServiceClient.Me.Request().GetAsync()

Error: Code: Request_ResourceNotFound

Message: Resource 'XXXX-XXXX-XXX-XXXX' does not exist or one of its queried reference-property objects are not present.

Have anyone faced this kind of error earlier, Can anyone suggest how to get the data for currently logged-in User using Microsoft Graph in C#?

You're using Client Credentials so there isn't a "currently logged-in User". It is actually the entire point of Client Credentials, authenticating an application without a user.

When using Client Credentials, you need to explicitly specify the User id or userPrincipalName:

var user = await graphServiceClient
    .Users["[email protected]"]
    .Request()
    .GetAsync();
