ROS websocker error. Unable to accept incoming connection. Reason: 'bson_only_mode'

edit

Hello,

I am trying to use baxter_web_interface package.

After launching roslaunch rosbridge_server rosbridge_websocket.launch I am trying to establish connection over port 9090 using webpage, it gives my those errors,

[INFO] [WallTime: 1489421469.154949] Rosbridge WebSocket server started on port 9090
[ERROR] [WallTime: 1489421864.967072] Unable to accept incoming connection. Reason: 'bson_only_mode'
[INFO] [WallTime: 1489421864.967882] Client connected. 0 clients total.

Any ideas how to solve that problem ?
