socket.io callbacks

[kwijibo]

When I use the socket.io engine, my socket.io server expects a callback to return data through, and crashes when Artillery is run (because Artillery does not provide a callback). I don't need to provide a custom callback, I just need Artillery to:

1. provide a callback so the server doesn't crash
2. measure the time taken to get a response via the callback

What is the stack trace for this error? I think I might be getting it too.
