Basic example doesn't detect camerma and hence no video

Hi Guys,
I am new to Licode community. I just installed the application on Ubuntu 16.04 and tested the basic app. I am not getting any video. The page is rendered. This is the URL --> http://192.168.1.117:3001/connection_test.html
I tested it on Mac using Chrome browser. I checked the console log and I see this:
Uncaught TypeError: can’t convert undefined to object
toLog erizo.js:2981
init erizo.js:3105
onload connection_test.js:83
onreadystatechange connection_test.js:24
erizo.js:2981:21
toLog erizo.js:2981
init erizo.js:3105
onload connection_test.js:83
onreadystatechange connection_test.js:24

Can someone please advise?

Thanks
