Ember.js: how to parse a bug in vendor.js

I have deployed my ember-cli app in a stage environment to let my teammates test the app. In an application I have implemented Ember.onerror

to email me errors that occur in stage and in production.

Ember.onerror = function(data) {
    Ember.$.ajax({
      type: "POST",
      url: url + "/error",
      dataType: 'json',
      contentType: 'application/json',
      data: JSON.stringify({message: data.message, stacktrace: data.stack}),
      beforeSend: function (xhr, settings) {
        xhr.setRequestHeader('Accept', settings.accepts.json);
      }
    });
  }

      

        
        
        
      

    

I am having difficulty parsing the stacktrace because it only references vendor.js and I can't figure out where the problem really is.

For example, I received the following message:

Message: Nothing handled the action 'back'. If you did handle the action, this error can be caused by returning true from an action handler in a controller, causing the action to bubble.

and stacktrace:

The meaning of the error message is clear, but I'm wondering if there is a way to easily find out where this action is back

not being processed.
