Server connection examples no longer working

[chrispoch]

I've tried the updated sample code in #7 (comment), updated to replace the IP and port with the IP I have mxGUI running on. I can use the Lawo Ember+ Viewer to see the tree on that IP/port.
The code in the comment has an extra ) on line 4 - client.connect()). If I remove the extra ), I get Uncaught TypeError TypeError: client.connect is not a function
It looks like connect() has been replaced with connectAsync(), but I get a stack dump when I run the code:

Any ideas of what I should be trying? I am hoping to make a port of https://github.com/castles/OSCWebMixer2 that works with Lawo mc^2 consoles but I am having trouble getting the node-emberplus to do anything useful - any pointers in the right direction would be much appreciated!
