I'm trying to deploy function only to firebase, here is the error:

+  functions: required API cloudfunctions.googleapis.com is enabled

Error: Error occurred while parsing your function triggers.

C:\Users\User\Documents\someapps\functions\nuxt.config.js:1
import colors from 'vuetify/es5/util/colors'
^^^^^^

SyntaxError: Cannot use import statement outside a module

The main error is: SyntaxError: Cannot use import statement outside a module.

Important part of the nuxt.config.js:

import colors from 'vuetify/es5/util/colors'

export default {
  vuetify: {
    customVariables: ['~/assets/variables.scss'],
    theme: {
      dark: false,
      themes: {
        light: {
          info: colors.teal.lighten1,
          warning: colors.amber.base,
        }
      }
    }
  }
}

The colors used by vuetify config among others, how to refactor import colors without error?

I've tried:

Transpile like the documentation suggest :

build: {
    transpile: ['vuetify/es5/util/colors'],
}

The error changed to ReferenceError: colors is not defined since I dunno where/how to define the colors without the import.
