private async Task LoginUser()

        var user = UserManager.GetUserByUsername(username);

        if (user != null)
        {
            var result = await SignInManager.PasswordSignInAsync(username, password, false, false);
            if (result.Succeeded)
            {
                NavigationManager.NavigateTo("/home");
            }
            else
            {
                validationMessage = "Invalid username or password.";
            }
        }       
    }

private async Task LoginUser()
    {
        var user = UserManager.GetUserByUsername(username);

        if (user != null)
        {
            var result = await SignInManager.PasswordSignInAsync(username, password, false, false);
            if (result.Succeeded)
            {
                NavigationManager.NavigateTo("/home");
            }
            else
            {
                validationMessage = "Invalid username or password.";
            }
        }       
    }

the result line is where it crashes and says object reference not set to an instance of an object and also the console error is in the image headers are read only response has already started anyone? top
