Blazor Server Redirect Causes blazor.web.js to not load from _framework correctly

I have a Blazor NET 8 Web Application. Currently working towards using Cookies as authentication. The login is being handled by a middleware class which does send the unauthorized user to /Login, but the blazor.web.js is not loading with an error of :

Uncaught SyntaxError: Unexpected token '<'

On a Status Code 302 Redirect

I have been looking all over for answers on how to resolve this.

Service Injection:

// Collection of Services to Inject into the Applicationpublic static IServiceCollection AddServerUI(this IServiceCollection services, IConfiguration config){    // Add LdapAuthenticationService    services.AddHttpContextAccessor();    services.AddScoped<AuthenticationStateProvider, CustomAuthenticationStateProvider>();    services.AddScoped<LdapAuthenticationService>();    // Bind LdapRoleMappings from configuration and add LdapRoleMappingConfig    var ldapRoleMappingConfig = new LdapRoleMappingConfig();    config.Bind("LdapRoleMappings", ldapRoleMappingConfig);    services.AddSingleton(ldapRoleMappingConfig);    var ldapServerList = new LdapServerList(config);    services.AddSingleton(ldapServerList);    // Adds Blazor Server render mode and components    services.AddRazorComponents()    .AddInteractiveServerComponents();    // Configure authentication    services.AddCascadingAuthenticationState();    services.AddScoped<CookieEvents>();    services.AddAuthentication("Cookies")        .AddCookie(options =>        {            options.LogoutPath = "/Logout";            options.AccessDeniedPath = "/AccessDenied";            options.ExpireTimeSpan = TimeSpan.FromMinutes(60); // Set the cookie expiration time            options.SlidingExpiration = true; // Enable sliding expiration            options.EventsType = typeof(CookieEvents);        });    // Configure authorization policies    services.AddAuthorization(options =>    {        options.AddPolicy("RequireAdminRole", policy =>            policy.RequireRole("Admin"));        options.AddPolicy("RequireUserRole", policy =>            policy.RequireRole("User"));        options.AddPolicy("RequireManagerRole", policy =>            policy.RequireRole("Manager"));        options.FallbackPolicy = new AuthorizationPolicyBuilder()        .RequireAuthenticatedUser()            .Build();       });    //services.AddSingleton<IAuthorizationMiddlewareResultHandler, AuthorizationMiddlewareResultHandler>();    // Mud Blazor UI Library Add In    services.AddMudServices();    services.AddMudBlazorSnackbar();    services.AddMudServicesWithExtensions();    // Add ThemeService    services.AddScoped<ThemeService>();    // Load Controllers from /Controllers Folder    services.AddControllers();    // IAppConfiguration holds Object with appsettings.JSON Loaded    services.AddSingleton<IAppConfiguration>(new ServerAppConfiguration(config));    // Http Client    services.AddHttpClient();    // Service to have run only in DEV mode.    #if DEV    #endif    return services;}// Build Configuration Injection for Applicationpublic static WebApplication ConfigureServer(this WebApplication app, IConfiguration config){    // Resolve IAppConfiguration from the services    var appConfiguration = app.Services.GetRequiredService<IAppConfiguration>();    // Middleware to set Path Base off BaseUrl in AppSettings.json Configuration    var baseUrl = appConfiguration.BaseUrl;    app.UsePathBase(baseUrl);    // Configure the HTTP request pipeline.    if (app.Environment.IsDevelopment())    {        app.UseDeveloperExceptionPage();    }    else    {        app.UseExceptionHandler("/Error", createScopeForErrors: true);    }    // Allow Loading of Static files from wwwroot folder    app.UseStaticFiles();    // Route Tables    app.UseRouting();    // Authentication and Authorization Configuration    app.UseAuthentication();    app.UseAuthorization();    app.UseAntiforgery();    app.UseHttpsRedirection();    /// Configuration loading for Controllers    app.MapControllers();    // Maps Components to the Application in Server Render Mode    app.MapRazorComponents<App>()            .AddInteractiveServerRenderMode();    return app;}

CustomAuthenticationStateProvider:

        private ClaimsPrincipal _currentUser = new ClaimsPrincipal(new ClaimsIdentity());        public override Task<AuthenticationState> GetAuthenticationStateAsync()        {            return Task.FromResult(new AuthenticationState(_currentUser));        }        public void NotifyAuthenticationStateChanged(ClaimsPrincipal user)        {            _currentUser = user;            NotifyAuthenticationStateChanged(Task.FromResult(new AuthenticationState(_currentUser)));        }

CookieEvents.cs:

   public override Task RedirectToLogin(RedirectContext<CookieAuthenticationOptions> context)   {       context.RedirectUri = "/Login";       return base.RedirectToLogin(context);   }

App.Razor:

<!DOCTYPE html><html lang="en"><head><meta charset="utf-8" /><meta name="viewport" content="width=device-width, initial-scale=1.0" /><base href="/" /><!-- CSS Library Imports  --><link href="_content/MudBlazor/MudBlazor.min.css" rel="stylesheet" /><link href="_content/MudBlazor.Extensions/mudBlazorExtensions.min.css" rel="stylesheet" id="mudex-styles"><HeadOutlet @rendermode="InteractiveServer" /></head><body><Routes @rendermode="InteractiveServer" /><div id="blazor-error-ui">        An unhandled error has occurred.<a href="" class="reload">Reload</a><a class="dismiss">🗙</a></div><!-- JS Library Imports  --><script src="_framework/blazor.web.js"></script><script src="_content/MudBlazor/MudBlazor.min.js"></script></script></body></html>

Routes.RazorSets Public Layout to use with /Login

<Router AppAssembly="typeof(Program).Assembly"><Found Context="routeData"><AuthorizeView><Authorized><RouteView RouteData="routeData" DefaultLayout="typeof(MainLayout)" /></Authorized><NotAuthorized><RouteView RouteData="routeData" DefaultLayout="typeof(PublicLayout)" /></NotAuthorized></AuthorizeView><FocusOnNavigate RouteData="routeData" Selector="h1" /></Found></Router>

Login.Razor

@page "/Login"@attribute [AllowAnonymous]

I have tried using this approach:

    public class AuthorizationMiddlewareResultHandler : IAuthorizationMiddlewareResultHandler    {        public Task HandleAsync(RequestDelegate next, HttpContext context, AuthorizationPolicy policy, PolicyAuthorizationResult authorizeResult)        {            return next(context);        }    }

But this doesn't enforce rerouting to /Login

Looking for some advice, I have seen various suggestions around this problem but nothing is really fixing the issue here:

Rerouting to /Login, but having blazor.web.js load in correctly after rerouting.

I have not found a specific solution that matches this problem, apologize if I missed something.
