Demo app fails to start

Hi Guys,
I am new to community. I configured the Licode server on ubuntu 16.04. I installed the demo app in a seperate VM running Ubuntu 16.04. When I try to start the demo app, I get the following error:
demo@demo:~/licode-demos$ sudo npm start
[sudo] password for demo:

application-name@0.0.1 start /home/demo/licode-demos
node app.js

/home/demo/licode-demos/node_modules/debug/src/node.js:132
let val = process.env[key];

This is my config.js file:
ar config = {};

config.nuve_host = ‘192.168.1.117’;
config.service = {};
config.service.id =‘531b26113e74ee30500001’;
config.service.key = ‘mykey’;

config.demo_host = ‘192.168.1.155’; // Without “http”, just the host.

config.http_port = 80;
config.https = false;
config.https_port = 443;
config.ca_certs = undefined;

//config.plain = true;

module.exports = config;
I randomly picked the service Id and key.

Please advise.

Thanks

I changed the nuve host entry in config.js file to http://192.168.1.117:3001 I got this error during the start of demo app:

application-name@0.0.1 start /home/demo/licode-demos
node app.js
