socks-tornado does not support path kwargs

[XxxUNIXxxX]

SockJS-Tornado is really cool project and I'm very glad to use it. But Ive got the problem related to the path kwargs . For example:

Everything works fine If I don't use named path kwargs:

ChatRouter = sockjs.tornado.SockJSRouter(ChatHandler, '/chat')

If I change the prefix like this:

ChatRouter = sockjs.tornado.SockJSRouter(ChatHandler, '/chat/(?P<room_id>[a-z0-9]{2,20})')

I will get the error When I try to connect to the chat:

Traceback (most recent call last):
  File "/Users/rlashchenkov/projects/env_msg/lib/python3.5/site-packages/tornado/web.py", line 1467, in _execute
    result = method(*self.path_args, **self.path_kwargs)
TypeError: get() got an unexpected keyword argument 'room_id'
