trying to setup on server : Uncaught TypeError: NAF.log.log is not a function

[franMx]

Changed line to display a warning instead (#13), but it seems server never connects to firebase? I get a Networked-Aframe connecting, but connected event is never fired (can run scene, but not multiplayer).

Hi, I followed the steps in "Running the example", but I get the error:

Uncaught TypeError: NAF.log.log is not a function

How can I fix it?
