target_cfg kwargs error when starting the nova-novncproxy server

[Naveen Joy]

I am getting a target_cfg kwargs error when I attempt to start the nova-novncproxy server. The root cause appears to be that the nova-novncproxy code is not passing in a required parameter ‘target_cfg’ to start the websocketproxyserver. I downloaded the websockify.py script from https://github.com/kanaka/websockify/blob/master/websockify .

sudo nova-novncproxy
