为什么当我不使用ConfigureHttps时，asp.net core 2.1 MVC中的TempData为null？

Question

I've tested TempData for sending data between two controllers, for example, SampleController to HomeController but it didn't work without ConfigureHttps. But when I marked the checkbox, ConfigureHttps TempData is executed correctly.why?

public class HomeController : Controller
{
    public IActionResult Sample()
    {
        return View();
    }

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

public class SampleController : Controller
{
    public IActionResult Sample2()
    {
        TempData["Name"] = "Ali";
        TempData["Family"] = "Amiri";
        return RedirectToAction("Sample", "Home");
    }
}

This code is for Sample's action in HomeController

@{
    ViewData["Title"] = "Sample";
}

<p>@TempData["Name"]</p>
<p>@TempData["Family"]</p>

I've found my problem, and I fixed it.I've commented this code and then TempData is worked without ConfigureHttps correctly.

  services.Configure<CookiePolicyOptions>(options =>{
        options.CheckConsentNeeded = context => true;
        options.MinimumSameSitePolicy = SameSiteMode.None;
});
