I think this has been addressed - if you download the zip file again. All you need to replace is the NodeServer.js file which you will see in the package directory if you don't want to change any of the other settings.
If that does not not resolve it let me know.
The issue has probably arisen in your setup because of an update to Node.js which is raising a new warning, ignored in previous versions.
Best wishes
