I am getting `Ember is not defined` errors in a lot of the files

[npendery]

The error I receive for a lot of the js files I try to update is:

error evaluating 'app/components/power-up-tile': Ember is not defined

Any idea why this might happen?

This is the command:

npx ember-native-class-codemod http://0.0.0.0:4200/ app/**/*.js

Same for me.
I also have no idea what 'path/to/server' should be - maybe that could fix it.
