Асинхронная ошибка при работе webflux со встроенным котом

Я изучаю webflux и tomcat 9. Я сделал простое приложение с одним методом (API).Мне удалось запустить его со встроенным котом.Но когда я запрашиваю метод, я получаю ошибку.

Вот мой код: 

    NewsRepository newsRepository = new DummyNewsRepository();
    NewsHandler newsHandler = new NewsHandler(newsRepository);
    RouterFunction<ServerResponse> newsRoute = route(GET("/news"), newsHandler::getNews);

    HttpHandler httpHandler = RouterFunctions.toHttpHandler(newsRoute);

    Servlet servlet = new ServletHttpHandlerAdapter(httpHandler);


    Tomcat server = new Tomcat();
    File base = new File(System.getProperty("java.io.tmpdir"));
    Context rootContext = server.addContext("", base.getAbsolutePath());
    Tomcat.addServlet(rootContext, "main", servlet);
    rootContext.addServletMappingDecoded("/", "main");
    server.setHostname("localhost");
    server.setPort(8080);
    server.getConnector();

    server.start();
    server.getServer().await();

И ошибка:
