I am trying to add a new user to db using the info i receive from google sign-in but i get errors

[Route("google-response")]
public async Task<ActionResult> GoogleResponse()
{

    var google_csrf_name = "g_csrf_token";
    var cookie = Request.Cookies[google_csrf_name];
    if (cookie == null)
        return StatusCode((int)HttpStatusCode.BadRequest);

    var requestbody = Request.Form[google_csrf_name];

    if (requestbody != cookie)
        return StatusCode((int)HttpStatusCode.BadRequest);

    var idtoken = Request.Form["credential"];
    GoogleJsonWebSignature.Payload payload = await GoogleJsonWebSignature.ValidateAsync(idtoken).ConfigureAwait(false);

    TempData["email"] = payload.Email;
    //return Json(payload);

    var user = new User { UserName = payload.Email, Email = payload.Email, IsEnabled = true, EmailConfirmed = true, DateRegister = DateTime.Now };
    await _userManager.CreateAsync(user).ConfigureAwait(false);
    // Sign-in the user
    await _signInManager.SignInAsync(user, isPersistent: false).ConfigureAwait(false);

    return RedirectToAction("Index","Home");

}

How to add new user? I have the following added in the controller:

public class HomeController : Controller
{

    private SignInManager<User> _signManager;
    private UserManager<User> _userManager;

    public HomeController(UserManager<User> userManager, SignInManager<User> signManager)
    {
        _userManager = userManager;
        _signManager = signManager;
    }

    private readonly ILogger<HomeController> _logger;

    public HomeController(ILogger<HomeController> logger)
    {
        _logger = logger;
    }

please advise

I managed to take off the error.

this is my home controller:

using ExpenseTracker.Models;
using Google.Apis.Auth;
using Microsoft.AspNetCore.Identity.UI.Services;
using Microsoft.AspNetCore.Identity;
using Microsoft.AspNetCore.Mvc;
using System.Diagnostics;
using Microsoft.PowerBI.Api.Models;
using System.Net;

namespace ExpenseTracker.Controllers
{
    public class HomeController : Controller
    {

        private readonly SignInManager<IdentityUser> _signManager;
        private readonly UserManager<IdentityUser> _userManager;

        public HomeController(UserManager<IdentityUser> userManager, SignInManager<IdentityUser> signManager)
        {
            _userManager = userManager;
            _signManager = signManager;
        }

        private readonly ILogger<HomeController> _logger;

        public HomeController(ILogger<HomeController> logger)
        {
            _logger = logger;
        }

        public IActionResult Index()
        {
            return View();
        }

        [ResponseCache(Duration = 0, Location = ResponseCacheLocation.None, NoStore = true)]
        public IActionResult Error()
        {
            return View(new ErrorViewModel { RequestId = Activity.Current?.Id ?? HttpContext.TraceIdentifier });
        }

        [Route("google-response")]
        public async Task<ActionResult> GoogleResponse()
        {

            var google_csrf_name = "g_csrf_token";
            var cookie = Request.Cookies[google_csrf_name];
            if (cookie == null)
                return StatusCode((int)HttpStatusCode.BadRequest);

            var requestbody = Request.Form[google_csrf_name];

            if (requestbody != cookie)
                return StatusCode((int)HttpStatusCode.BadRequest);

            var idtoken = Request.Form["credential"];
            GoogleJsonWebSignature.Payload payload = await GoogleJsonWebSignature.ValidateAsync(idtoken).ConfigureAwait(false);

            TempData["email"] = payload.Email;

            //return Json(payload);

            var user = new IdentityUser { UserName = payload.Email, Email = payload.Email };
            await _userManager.CreateAsync(user).ConfigureAwait(false);
            return RedirectToAction("Index","Home");

        }
    }
}
