Duende Identity Server 4 doesn't redirect back to the React client at the end of sign in workflow

Question

I'm implementing authentication using Duende Identity Server based on CODE grant type. I need Identity Server to issue tokens for my React Client App, I added react-oidc-context to the Client App as OpenId Connect client. Also I've configured IS to add a few test users on startup for test purposes and added base UI. The issue is that when I enter test user's credentials to login form on IS and click Login button I see the name of user I just logged in by at the top of the login page, but IS doesn't redirect me back to the Client App, it just refreshes the login page. I was wondering if you could provide any information regarding the possible solutions or issue's causes. Thank you in advance!

Here is the screenshot of page I see after clicking login button: Login page after signing in as a test user

Here is my config for Identity Server resources:

new Client
{
    ClientId = "spa",
    ClientName = "React Single Page Application",
    ClientSecrets = { new Secret("secret") },
    RequireClientSecret = false,
    ClientUri = "https://localhost:44430",
    RedirectUris = { "https://localhost:44430/fetch-data" },
    PostLogoutRedirectUris = { "https://localhost:44430" },
    AllowedGrantTypes = GrantTypes.Code,
    RequirePkce = false,
    AllowAccessTokensViaBrowser = true,
    AllowedScopes =
    {
        IdentityServerConstants.StandardScopes.OpenId,
        IdentityServerConstants.StandardScopes.Profile,
        "weather",
    },
},

Here is my config that I use for connecting to IS on the Client App side:

{
    authority: "https://localhost:7123",
    client_id: "spa",
    client_secret: "secret",
    redirect_uri: "https://localhost:44430/fetch-data",
    post_logout_redirect_uri: 'https://localhost:44430',
    response_type: 'code',
    scope: 'weather',
    userStore: new WebStorageStateStore({ store: window.localStorage }),
};

Also here is config of IS service in the program.cs file:

builder.Services.AddIdentity<AppUser, IdentityRole>()
    .AddEntityFrameworkStores<AppIdentityDbContext>()
    .AddDefaultTokenProviders();

builder.Services.AddIdentityServer(options =>
    {
        options.IssuerUri = "https://localhost:7123";

        options.Events.RaiseErrorEvents = true;
        options.Events.RaiseInformationEvents = true;
        options.Events.RaiseFailureEvents = true;
        options.Events.RaiseSuccessEvents = true;
        options.EmitStaticAudienceClaim = true;
    })
    .AddInMemoryIdentityResources(Config.GetIdentityResources())
    .AddInMemoryApiScopes(Config.GetApiScopes())
    .AddInMemoryApiResources(Config.GetApisResources())
    .AddInMemoryClients(Config.GetClients(builder.Configuration))
    .AddTestUsers(TestUsers.Users)
    .AddAspNetIdentity<AppUser>();

To fix the issue I've tried switching all endpoints to use https. Also I've tried to set up cookie policy in IS porgram.cs, below is config that I added:

app.UseCookiePolicy(new CookiePolicyOptions
{
    HttpOnly = HttpOnlyPolicy.None,
    MinimumSameSitePolicy = SameSiteMode.None,
    Secure = CookieSecurePolicy.Always
});

Updated

After some time spent on investigation I've finally came up with solution: The issue was caused by default implementation of login page model (Pages/Account/Login/Index.cshtml/Index.cshtml.cs).I've injected SignInManager signInManager to the page's model and used it as users storage instead of default TestUserStore, that fixed the issue.
