Процесс авторизации с PKCE: Отображение логина: пользователь не аутентифицирован

Мы настроили спа-центр vueJs, работающий на узле в его собственном домене.

Мы настроили приложение IdentityServer4 ядра asp.net в другом домене.

Мы пытаемся использовать код авторизации PKCE flow.

Мы просмотрели несколько статей, но большинство из них имеют другую конфигурацию, используя либо неявный поток, либо клиент MVC в том же домене.

Вот конфиг клиента:

import Oidc from 'oidc-client';

   var mgr = new Oidc.UserManager({
     authority: "https://localhost:44363",
     client_id: 'Code Autho',
     redirect_uri: 'http://localhost:8080',
     response_type:'code',
     scope: 'openid profile email api1',  
})

export default mgr;

Вот клиент, созданный в конфигурации IdentityServer:

           new Client
            {
                ClientId = "Code Autho",
                ClientName = "Code With PKCE",
                RedirectUris = {
                    Uri.EscapeUriString("http://localhost:8080")
                },
                PostLogoutRedirectUris = {"http://localhost:8080"},
                RequireClientSecret = false,
                AllowedGrantTypes = GrantTypes.Code,
                RequirePkce = true,
                AllowedScopes = {
                    IdentityServerConstants.StandardScopes.OpenId,
                    IdentityServerConstants.StandardScopes.Profile,
                    IdentityServerConstants.StandardScopes.Email,
                    "api1"
                },
                AllowOfflineAccess = true,
                RefreshTokenUsage = TokenUsage.ReUse
            }

Ожидается: мы перенаправляемся на http://localhost:8080 И пользователь аутентифицирован. (У нас есть компонент входа в систему на localhost: 8080, ожидающий имени пользователя / пароля).
