Got errors over connecting

[geohuz]

Run with the test.lua in the project, get the following error:

Connecting client to WAMP Server: ws://xxxx/ws/
[DEBUG] (string) "websocket OnOpen event fired"

CALLBACK FAILED: /Users/mac/.luarocks/share/lua/5.2/loowy/client.lua:497: bad argument #1 to 'match' (string expected, got nil)
stack traceback:
	[C]: in function 'match'
	/Users/mac/.luarocks/share/lua/5.2/loowy/client.lua:497: in function '_wsOnOpen'

the 497 line in client.lua:

options.transportEncoding = string.match(wsProtocol,'.*%.([^.]+)$')

the wsProtocol is nil, can't figure out how to fix it. (If I comment out the 497 line it runs without problem)

Hi! Hm... What version of lua-websockets do you use? I suppose it is due to that lua-websockets version used doesn't return subprotocol headers...

2.2 I suppose
