Nuxt SSR - Firebase Hosting - firebase

Question

Going through the gauntlet of deploying a Nuxt SSR app to firebase hosting. I've been following this fantastic tutorial. Due to Firebase's limitations with es6-es7, I'm converting my "imports" to "require" and "module.exports". For some reason, when I run firebase deploy --only functions, the deploy fails with the following error:
import colors from 'vuetify/es5/util/colors'
^^^^^^
SyntaxError: Cannot use import statement outside a module

When I check the error locations, I see that the code that I had manually changed to ES5 syntax has been auto-reverted to ES7 syntax. My first thought was that this could be an eslint issue, but I'm note sure.
PACKAGE.JSON Scripts
"scripts": {
"lint": "eslint",
"serve": "firebase emulators:start --only functions",
"shell": "firebase functions:shell",
"start": "npm run shell",
"deploy": "firebase deploy --only functions",
"logs": "firebase functions:log"
},
.ESLINT.JS
module.exports = {
root: true,
env: {
es6: true,
node: true,
},
extends: [
"eslint:recommended",
"google",
],
rules: {
quotes: ["error", "double"],
},
};
Has anyone else experienced this issue while trying to deploy Nuxt SSR to Firebase Hosting via a Cloud Function?
