Error when import diffusion

Hi, in 6.9.0 version, i receive the error when import diffusion.

No error notification when wrong Topic name given

Im using diffusion sdk 5.9.0 and able to connect and subscribe to topic is correct connection props and topic name are given.
Now, if i give incorrect topic name to session.subscribe function I don't get any error event on my session. Can you help how can i get the error event in above case?

onClose not called in missing topic handler

When closing the client session from the Diffusion console, MissingTopicNotificationStream#onClose() is never called. However, if I use MissingTopicHandler#onClose(), which is marked as deprecated, it is called.

// works
topicControl.addMissingTopicHandler(topic, new TopicControl.MissingTopicHandler() {
    @Override
    public void onMissingTopic(TopicControl.MissingTopicNotification missingTopicNotification) {
        logger.info("request: {}", missingTopicNotification.getTopicPath());
    }

    @Override
    public void onActive(String s, RegisteredHandler registeredHandler) {
        logger.info("active");
    }

    @Override
    public void onClose(String s) {
        logger.error("close"); // it's called!
    }
});

// doesn't work
topicControl.addMissingTopicHandler(topic, new TopicControl.MissingTopicNotificationStream() {
    @Override
    public void onMissingTopic(TopicControl.MissingTopicNotification missingTopicNotification) {
        logger.info("request: {}", missingTopicNotification.getTopicPath());
    }

    @Override
    public void onError(ErrorReason errorReason) {
        logger.error("error");
    }

    @Override
    public void onClose() {
        logger.error("close"); // it's not called!
    }
});

Client version: implementation 'com.pushtechnology.diffusion:diffusion-client:6.8.9'
Server version: 6.8.9

(the same behavior is observed on higher versions).

Node client

The JS examples require diffusion node client, version on github is too old, are you going to provide a diffusion node js file to run the examples?
