Find the error in the code

Hi Professional coders, [login to view URL] The above link is for the apk of the code. [login to view URL] This link is the link to download the code itself. The above application is made in Meteor, javascript based framework. It will let user to remotely access their smart phone's features from the desktop. User only has to scan the QR code present on the web app from mobile. The code uses WebRTC mainly with cordova plugins to send sms, QR scan, copy text to mobile's clipboard, accessing files and folders etc. Operating system required may either be linux or mac in order to build and test the app on android/ios. [login to view URL] This link has all the information and dependencies of how to run and build a meteor app on android and ios. We need to run it on android in specific as we do not have mac available. *Problem the application is causing is that it is not establishing any connection after the QR scan. Though it runs without any errors. Neither it is showing anything on the console log in browser while scanning the QR code. If QR Scan doesn't works, no feature can be accessed as no connection will be established between the smart phone and the computer. That needs to be fixed. Ubuntu terminal shows this error after starting the app successfully. This might be the problem but I am not sure. So look into it if this is the root cause. meteor run android-device -p 3000 --verbose this is the command I am using to run this application from ubuntu terminal to my android device, the app runs on localhost:3000 in the browser check attached screen shot, and tell whats the error in code why its not scanning If have any queries, feel free to ask.
