Hi Dmitry,

It’s in a plugin. You can probably prove it by going safe-mode.

You got to find in which plugin it’s happening, and deactivate it. It shouldn’t be one of our officials plugin.

The fix is probably going to be simple [Ember.js - Deprecations](https://deprecations.emberjs.com/v2.x#toc_migrating-from-_lookupfactory-to-factoryfor)
