Any way to get meaningful errors in the Ember CLI?

I am using the Ember CLI and I have a problem in my code that has to do with computed aliases and model relationships. I cannot debug this issue as I am getting errors like this:

"EmberError@http://localhost/assets/vendor.js:22707:15
Ember.default.assert@http://localhost/assets/vendor.js:15408:13
ember$data$lib$system$store$finders$$_find/<@http://localhost/assets/vendor.js:63941:9
tryCatch@http://localhost/assets/vendor.js:55993:16
invokeCallback@http://localhost/assets/vendor.js:56005:17
publish@http://localhost/assets/vendor.js:55976:11
@http://localhost/assets/vendor.js:37026:7
Queue.prototype.invoke@http://localhost/assets/vendor.js:11432:11
Queue.prototype.flush@http://localhost/assets/vendor.js:11497:13
DeferredActionQueues.prototype.flush@http://localhost/assets/vendor.js:11302:13
Backburner.prototype.end@http://localhost/assets/vendor.js:10727:11
Backburner.prototype.run@http://localhost/assets/vendor.js:10782:15
executeTimers@http://localhost/assets/vendor.js:11164:7
updateLaterTimer/backburner._laterTimer<@http://localhost/assets/vendor.js:11153:11
"

Is there a way to get nicer errors? Even simple javascript exceptions would be better than this.

I have this in my console:

"DEBUG: -------------------------------" vendor.js:15442:4
"DEBUG: Ember      : 1.12.0" vendor.js:15442:4
"DEBUG: Ember Data : 1.0.0-beta.17" vendor.js:15442:4
"DEBUG: jQuery     : 1.11.3" vendor.js:15442:4
"DEBUG: -------------------------------"
... Some deprecations messages from Ember Data that is irrelevant
"Ember Inspector Active"
... The error above

You're looking at an ember app that was built for production ...

To debug application launch ember server



Then you will get the original displayed output

I have the same problem and honestly I don't think there is a way to get better stack traces.



Your best bet is to try to add breakpoints using debugger;

where you suspect the error is expanding, then checking your code at runtime.

I think this issue is related to Firefox bug https://bugzilla.mozilla.org/show_bug.cgi?id=670002 . In my development environment the console.log shows the vendor.js line number (not desired), but through debugging I can see the sources of my project.

Have you tried debugging sources? The debugger tab should display all application files and some of the different addons. I have ember 2.4.4.
