在AWS Lambda中订阅后，Salesforce emp连接器不等待事件

Question

我有一个使用Salesforce EMP连接器并订阅平台事件的简单客户端。当我在Windows计算机上从命令行运行它时，它可以正常工作，并且订阅和后续事件也可以正常工作。 当我在AWS中部署与Java Lambda函数相同的代码时-它成功预订但不等待/监听事件。在AWS Lambda中使用Java Bayeaux客户端有一些限制吗？

下面是Lambda处理程序中的代码-

 public String handleRequest(Object input, Context context) {
        try {
        context.getLogger().log("Input: " + input);

        Consumer<Map<String, Object>> consumer = event -> System.out.println(String.format("Received:\n%s", JSON.toString(event)));

        BearerTokenProvider tokenProvider = new BearerTokenProvider(() -> {
            try {
                return LoginHelper.login(new URL(SFDC_TEST_URL), SFDC_TEST_USERNAME, SFDC_PASS_SEC_KEY);
            } catch (Exception e) {
                throw new RuntimeException(e);
            }
        });

        BayeuxParameters params = tokenProvider.login();

        EmpConnector connector = new EmpConnector(params);
        LoggingListener loggingListener = new LoggingListener(true, true);


        connector.addListener(META_HANDSHAKE, loggingListener)
                .addListener(META_CONNECT, loggingListener)
                .addListener(META_DISCONNECT, loggingListener)
                .addListener(META_SUBSCRIBE, loggingListener)
                .addListener(META_UNSUBSCRIBE, loggingListener);


        connector.setBearerTokenProvider(tokenProvider);


        connector.setBearerTokenProvider(tokenProvider);

        connector.start().get(5, TimeUnit.SECONDS);

        TopicSubscription subscription = connector.subscribe(SFDC_TOPIC_EVENT_NAME, EmpConnector.REPLAY_FROM_TIP, consumer).get(2, TimeUnit.SECONDS);

        System.out.println(String.format("Subscribed: %s", subscription));

        // TODO: implement your handler
        return "Hello from Lambda!";
        }catch(Exception e) {
            e.printStackTrace();
            return "exited with error";
        }
    }
