[1747] TypeError when using Bookshelf.js

I have been trying to get Vuex (inside of Nuxt.js) to work with a SQLite database using Bookshelf.js and Knex.js. I have been able to get Bookshelf to function outside of Nuxt, but when I put the same code inside of Nuxt, I get this in my browser console upon running a model:

bluebird.js:1542

I am using the same setup I used outside of Nuxt, but now it isn't working. This makes me think that the issue is on Nuxt's side.

P.S. If I am doing anything wrong or if there is a better way to achieve this (have Vuex interact with a database), please tell me

To reproduce error (may upload repo in the morning; getting late): 1. Make a new Nuxt project

vue init nuxt/starter bug-test
cd bug-test
npm install

2. Install Bookshelf, etc.

npm install bookshelf knex
npm install sqlite3@3.1.11 --save-exact # 3.1.12 causes bug which makes it impossible to `npm install`

3. Add database folder (for organization)

mkdir database
cd database

4. Add an empty SQLite database

sqlite3 db.sqlite
# SQLite version 3.20.1...
sqlite> create table blank; # not adding columns causes it to fail but still write a file; not best method but works
sqlite> .exit

5. Add Bookshelf.js files (add these to database/ directory; same as db.sqlite)

   1. knexfile.js

      module.exports = {
        client: 'sqlite3',
        connection: {
          filename: 'db.sqlite'
        },
        useNullAsDefault: true
      }

   2. bookshelf.js

      let knex = require('knex')(require('./knexfile'))
      
      let bookshelf = require('bookshelf')(knex)
      
      module.exports = bookshelf

   3. migrations/users.js

    exports.up = function (knex) {
      return knex.schema
        .createTable('users', table => {
          table.increments('id').primary()
          table.string('firstName')
          table.string('lastName')
          table.string('emailAddress')
        })
    }
   
    exports.down = function (knex) {
      return knex.schema
        .dropTable('users')
    }

   4. models/users.js

      var bookshelf = require('../bookshelf')
      
      var Users = bookshelf.Model.extend({
       tableName: 'users'
      })
      
      module.exports = Users

6. Add new page

<template lang="html">
  <section>
    <h1>Testing Page</h1>
    <pre>{{users}}</pre>
  </section>
</template>

<script>
import Users from '~/database/models/users'

export default {
  computed: {
    users () {
      let users
      Users.fetchAll().then(function (contact) { users = contact.toJSON() })
      return users
    }
  }
}
</script>

7. Migrate and start it up

cd ../ # if still in database/ or pages/
./node_modules/.bin/knex migrate:latest --knexfile database/knexfile.js
npm run dev

8. Open http://localhost:3000/testing (or whatever you called your page) in a browser and open console

Any help/feedback appreciated
