如何在 UserManager CreateAsync 中查看 Controller 中出现的错误？

Question

I am trying to create user with UserManager and CreateAsync method, but it doesn't work. Im postman I always get 200 OK

My Post method

        [HttpPost]
        public async Task<IActionResult> Register()
        {
            User user = new User { Email = "asfa@gmail.com", UserName = "asfa@gmail.com" };
            var result = await _userManager.CreateAsync(user, "SS22!faasd");
            if (result.Succeeded)
            {
                // install cookie
                await _signInManager.SignInAsync(user, false);
            }
            else
            {
                foreach (var error in result.Errors)
                {
                    //how can i see my errors here
                }
            }
            return Ok();
        }

Also I dont have any cshtml files, so I cant output them on page. Or you can just explain, why my CreateAsync method doesn't work.

You could just return the result from the server every time:

return Ok(result);

It will be serialized so you can see it.
