Roslibjs publish topic error

I set up the roslibjs exactly as the tutorial suggets, and subscribing is working great ( I am able to connect to the websocket, etc). However, whenever I try to publish I get an error in the rosbridge websocket below:

[ERROR] [15.500000] [/rosbridge_websocket]: [Client 7] [id: publish:/cmd_vel:2] publish: 'type'

I am using the indigo release of ROS & Ubuntu 14.04, and the current version of both eventransmitter & roslibjs from the CDN Here is the link:http://wiki.ros.org/roslibjs/Tutorials/BasicRosFunctionality

Could you provide more info. like the image of your terminal, and also the javascript code just to be sure that it is indeed the same as the one in the tutorial.
