Socket.io Cannot read property 'encode' of undefined #48

Hi, I am try to install loopback-connector-mongodb for my socket.io. And after that, I got error like this

this.encoder.encode(packet, function(encodedPackets) {
^
TypeError: Cannot read property 'encode' of undefined

After I find out, it turns out this error caused by socket.io plugin that is installed in @mean-expert/loopback-component-realtime is version 1.7.x.
So after I update the manual to version 2.x, the error does not reappear.

Maybe you can fix that?
Thanks,
Imron
