Forbidden page

Hi guys, I've tried to use Cookie Authentication, so:

Configure Method:

app.UseCookieAuthentication(new CookieAuthenticationOptions()
{
	AuthenticationScheme = "UwpCookieMiddlewareInstance",
	LoginPath = new PathString("/Account/Unauthorized/"),
	AccessDeniedPath = new PathString("/Account/Forbidden/"),
	AutomaticAuthenticate = true,
	AutomaticChallenge = true,
})

app.Run(async context =>
{
	var user = context.User;

	// Deny anonymous request beyond this point.
	if (user == null || !user.Identities.Any(identity => identity.IsAuthenticated))
	{
		await context.Authentication.ChallengeAsync();

		return;
	}
});

ConfigureServices method:

services.AddAuthentication(options => options.SignInScheme = CookieAuthenticationDefaults.AuthenticationScheme);

SignIn action:

const string uwpCookieMiddlewareInstance = "UwpCookieMiddlewareInstance";

public async Task<IActionResult> SignIn()
{
	var claimsPrincipal = new ClaimsPrincipal();

	var claimsIdentity = new ClaimsIdentity();

	var claim = new Claim("login", "urban.michal@icloud.com");

	claimsIdentity.AddClaim(claim);

	claimsPrincipal.AddIdentity(claimsIdentity);

	await HttpContext.Authentication.SignInAsync(uwpCookieMiddlewareInstance, claimsPrincipal);

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

and when I'm executing this action and when [Authorize] attribute is added to Home controller it's get redirected to Forbidden page. When I get rid of attribute, access is granted. When I set attribute in that way:

[Authorize(CookieAuthenticationDefaults.AuthenticationScheme)

Server returns such exception:

Any ideas what I'm doing wrong or what is omitted?
