@yuhuisg is correct, this is a Javascript issue occurring with some of your custom code; without seeing that code, or what it's trying to do this is very hard to diagnose.
If you turn on the Satellite Debugger, you should be able to identify which rule in Launch is potentially throwing the issue.. but the probably could be part of a Data Element used by that rule.
To turn on/off the Satellite Debugger:
// Turn On
_satellite.setDebug(true);
// Turn Off
_satellite.setDebug(false);
It won't find the issue, but it might help you narrow down where to start looking.
You could also try searching in your Launch property for "ga" but given this combination would probably show up commonly as a word within a word, I am not sure if it will help much.
