supabase.Auth.CurrentSession returns null , c# client

Question

I'm using dotnet add package supabase-csharp as a c# client. I'm signed in var session = await supabase.Auth.SignIn(email, password); successfully, but when i tried to get the current user or session it get back as null:

var currentSession = _supabase.Auth.CurrentSession;
var currentUser = _supabase.Auth.CurrentUser;

The configuration:

builder.Services.AddScoped<Supabase.Client>(_ =>

new Supabase.Client(
    builder.Configuration["SUPABASE_URL"],
    builder.Configuration["SUPABASE_KEY"],
    new SupabaseOptions
    {
        AutoRefreshToken = true,
        AutoConnectRealtime = true,
    }));

Any hints related to this?

Instead of accessing them directly after login, try fetching them after login is complete. var session = await _supabase.Auth.SignIn(email, password); if (session != null) { var currentSession = _supabase.Auth.CurrentSession; var currentUser = _supabase.Auth.CurrentUser; } — erray

The idea is that i have separated endpoints for each action: One controller for : signup, signin, signout. And another controller for : currentsession, currentuser, update. Sample: [HttpGet("currentuser")] public IActionResult GetCurrentUser() { try { var currentUser = _supabase.Auth.CurrentUser; return Ok(currentUser); } catch (Exception ex) { return BadRequest(new { Error = $"Error getting current user: {ex.Message}" }); } } — mark02

the problem is AddScoped, so when the request ends and you request a new one, you have lost authentication. — Angelru

You can use the _supabase.Auth.GetUser(jwt) method to retrieve the current user with their token

// get JWT token from request header
var token = _httpContextAccessor.HttpContext.Request.Headers["Authorization"].ToString().Replace("Bearer ", "");
var user = await _supabase.Auth.GetUser(token);

With this you can access the signed in User 's object
