emberjs ember-resolver error on production

We just migrated our project from ember-resolver 2.0.3 to ember-resolver 5.0.1. We also updated ember-cli from 2.9.1 to 3.3.0. All of our environments work as they should except production.

We are getting an error of Could not find module 'ember-resolver' imported from ...

I saw that this was an issue back when users upgraded from 2.12 --> 2.17.

Anyone else getting something similar?
