title: How do I debug a "[object ErrorEvent] thrown" error in my Karma/Jasmine tests?
body: <p>I have several failing tests that only output <code>[object ErrorEvent] thrown</code>.  I don't see anything in the console that helps me pinpoint the offending code.  Is there something I need to do to track these down?</p>
  
  <p>[EDIT]: I'm running Karma v1.70, Jasmine v2.7.0</p>
