There’s a lot going on here and this is going to be a rough upgrade path. Let’s take things one step at a time. First we probably need some more information though.

at engine.js Are you using ember-engines? It looks like it from this but not sure

dag-map.js where does dag-map come from? is it from a third party package or is that part of your app code?

General questions:

  • have you updated your dependencies to the newest versions that are compatible with your ember versions? this always helps a lot when upgrading
  • have you cleared any deprecation warnings? there were a number of things removed in the middle of the 2.x versions which can break things if your code or addons still rely on them

Yes I’m using ember-engines.

dag-map.js is third party package

jQuery has installed in bower dependencies.

yes first I upgraded from 2.7 to 2.12 and cleared all deprecations. next I tried to move from 2.12 to 2.16 , still getting the same error.

I can’t completely remember but i think around this time the way jquey got bundled within ember-source i think so what is likely happening is you have a package that is extending jquery but you are using the ember jquery instead, as this is happening in the initalizier i think you may need to check the import to make sure you are using the correct version.
