EasyRTC inside Meteor error

I am trying to run a second EasyRTC server and access this server inside Meteor. This is the tutorial I am working from:

<https://easyrtc.com/docs/easyrtc_with_other_servers.php>

The program works fine within a basic express server, so my problem must have something to do with Meteor. These are my browser console errors:

```
Exception in defer callback: bad video element id undefined  meteor.js:994:11
Exception from Tracker recompute function:  meteor.js:992:11
undefined  meteor.js:994:11

```

So the first question is, where is the meteor.js file, so I can at least see where my error is coming from?
