Thanks. I got the answer.
I found the reasion is that the code'location
services.AddServiceStack(typeof(MyServices).Assembly);

public class AppHost : AppHostBase, IHostingStartup
{
    public void Configure(IWebHostBuilder builder) => builder
        .ConfigureServices(services => {
            // I need move this line to Program.cs
            services.AddServiceStack(typeof(MyServices).Assembly);
        });

    public AppHost() : base("IssueValidationSource", typeof(MyServices).Assembly) {}

    public override void Configure(Container container)
    {
        SetConfig(new HostConfig {
                UseSameSiteCookies = false,
        });
    }
}
