This looks like a standard JavaScript error, likely coming from a custom code module in your Launch implementation.
Without seeing your code, there is nothing we can do to help solve it.
However, to help you track down the issue. I suggest that you enable the Satellite Debugger so you can see which rules are firing and when to help track down where that code may be.
To turn on and off debugger:
// Turn it on
_satellite.setDebug(true);
// Turn it off
_satellite.setDebug(false);
Good luck tracking this down.
