Drupal chat not working with node.js - rewrite for new nodejs module

This is weird.
I can get drupalchat working with the ajax backend method, but not nodejs.
Nodejs is working for everything else.

Same issue here, it seems this is only compatible with older versions of nodejs? 3 years ago, so not sure, trying to get this to work myself.

In addition nodejs 7.12 has been refactored.

So are we beating a dead horse here trying to get this to work with the latest versions of nodejs?

I am running:
Drupal nodejs: 7.x-1.12
Drupal Chat: 7.x-1.8
Nodjs: v4.3.1
nmp : 2.14.12

My nodeserver is running and logging correctly as far as i can see before I add the chat extension. I renamed my extension file to chat_nodejs.server.extension.js

When adding the extension I can see it gets loaded ie:
Extension loaded: /chat_nodejs.server.extension.js
Started http server.

But then also produces the following error:

[sitepath]/modules/contrib/nodejs/node_modules/drupal-node.js/lib/client-manager.js:797
if (this.sockets[sessionId]) {
^

TypeError: Cannot read property 'sockets' of undefined

My config file:

backendSettings = {
"scheme": "http",
"host": "localhost",
"port": 8888,
"key": "/path/to/key/file",
"cert": "/path/to/cert/file",
"resource": "/socket.io",
"publishUrl": "publish",
"serviceKey": "",
"backend": {
"port": 80,
"host": "localhost",
"messagePath": "/[sitename]/nodejs/message"
},
"clientsCanWriteToChannels": false,
"clientsCanWriteToClients": false,
"extensions": ["/chat_nodejs.server.extension.js"],
"debug": true,
"transports": ["websocket",
"polling"],
"jsMinification": true,
"jsEtag": true,
"logLevel": 1
};

Please note im just using [sitename] as a ref... I also tried adding the extension to the root of the app, and not in the extensions folder... same result.

I can confirm this error.

I can confirm this too

I change drupalchat to use Node.js , I cant see any users...

There is a new rewrite of nodejs and drupalchat needs to be updated.
