错误：端点客户端缺少必需的“ URL”参数

如何解决错误：端点客户端缺少必需的“ URL”参数

我有一个项目netcoreapp5.0，在我迁移到最后一个netcoreapp5.0后，Kestrel出现了问题：

错误抛出于CreateHostBuilder(args).Build().Run();

抛出的错误是

"The endpoint Clients is missing the required 'Url' parameter." 

我已经安装了最后一个SDK。

Program.cs＆Startup.cs

public static void Main(string[] args)
{
    CreateHostBuilder(args).Build().Run();
}

public static IHostBuilder CreateHostBuilder(string[] args) =>
    Host.CreateDefaultBuilder(args)
        .ConfigureWebHostDefaults(webBuilder =>
        {
            webBuilder.UseStartup<Startup>();
            webBuilder.UseKestrel(options => {
                options.Listen(IPAddress.Any,50003);
                options.Limits.MaxRequestBodySize = null;
            });
        });


public class Startup
{
    public Startup(IConfiguration configuration)
    {
        Configuration = configuration;
    }

    public IConfiguration Configuration { get; }

    // This method gets called by the runtime. Use this method to add services to the container.
    public void ConfigureServices(IServiceCollection services)
    {
        services.AddDbContext<SqlServerApplicationDbContext>(options =>
            options.UseSqlServer(
                Configuration.GetConnectionString("DefaultConnection")));


        services.AddDefaultIdentity<MyApplicationUser>(options => options.SignIn.RequireConfirmedAccount = true)
            .AddEntityFrameworkStores<SqlServerApplicationDbContext>()
            .AddDefaultUI()
            .AddDefaultTokenProviders();



        services.AddControllersWithViews();
        services.AddRazorPages();
    }

    // This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
    public void Configure(IApplicationBuilder app,IWebHostEnvironment env)
    {
        if (env.IsDevelopment())
        {
            app.UseDeveloperExceptionPage();
        }
        else
        {
            app.UseExceptionHandler("/Home/Error");
            // The default HSTS value is 30 days. You may want to change this for production scenarios,see https://aka.ms/aspnetcore-hsts.
            app.UseHsts();
        }
        app.UseHttpsRedirection();
        app.UseStaticFiles();

        app.UseRouting();

        app.UseAuthentication();
        app.UseAuthorization();

        app.UseEndpoints(endpoints =>
        {
            endpoints.MapControllerRoute(
                name: "default",pattern: "{controller=Home}/{action=Index}/{id?}");
            endpoints.MapRazorPages();
        });
    }
}
