Cannot read property 'scope' of null

[btecu]

Using Ember 1.13.5 and Ember Data 1.13.7.

When I open the ember-inspector I get the multiple exceptions:

VM3546:94 Deprecations were detected, see the Ember Inspector deprecations tab for more details.

It seems very related to #416.
After looking into it I found that the problem seems to be here:

    _controllerForNode: function(renderNode) {
      return renderNode.lastResult.scope.locals.controller.value();
    }

Sometimes renderNode.lastResult is undefined.
Just adding renderNode.lastResult && seemed to not fix it.

Any other ideas?

It seems that this issue occurs when using Ember.onerror. Can't seem to be able to replicate it on an empty repo.

@jcope2013 are you using Ember.onerror?

[jcope2013]

@btecu yeah

[btecu]

@jcope2013 Can you try commenting Ember.onerror and check if you still have issues with the ember-inspector?

Maybe related: I'm getting Uncaught TypeError: Cannot read property 'responseText' of null when I try to load deprecations lists on EI. Removed ember-cli-sentry (wich AFAIK is the only code that uses Ember.onerror) and nothing new.

Ember 1.13.5
Ember Data 1.13.7

@amedrz this is a different issue. Can you please open a separate issue for your error so we can track it?

@teddyzeenny after digging deeper I noticed it's caused by ember-offline and filed an issue ahmadsoe/ember-offline/issues/1
