.insertOne is not a function

Question

I want to preface this by saying I have read several posts here regarding this issue.

I have a node/express/mongo app with the following:

app.js:

    var express = require('express')
    var bodyParser = require('body-parser')
    var cors = require('cors')
    var morgan = require('morgan')
    var mongoose = require('mongoose')
    var passport = require('passport')

    var app = express()

    // MongoDB Setup
    var configDB = require('./config/database.js')
    mongoose.connect(configDB.url)

    app.use(morgan('combined'))
    app.use(bodyParser.json())
    // Check security with this
    app.use(cors())
     // load our routes and pass in our app and fully configured passport

    require('./routes')(app)
    app.listen(process.env.PORT || 8081)
    console.log('We are up and running, captain.')

routes.js

const AuthenticationController = require('./controllers/AuthenticationController')

module.exports = (app) => {
  app.post('/register', AuthenticationController.register)
}

My mongo schema file Account.js:

const mongoose = require('mongoose')
const bcrypt = require('bcrypt-nodejs')
const Schema = mongoose.Schema

var accountSchema = new Schema({
  email: String,
  password: String,
  likesPerDay: { type: Number, min: 0, max: 250 },
  followPerDay: { type: Number, min: 0, max: 250 },
  unfollowPerDay: { type: Number, min: 0, max: 250 },
  commentsPerDay: { type: Number, min: 0, max: 250 },
  comment: String,
  hashtags: [String]
})

// methods ======================
// generating a hash. We hash password within user model, before it saves to DB.
accountSchema.methods.generateHash = function (password) {
  return bcrypt.hashSync(password, bcrypt.genSaltSync(8), null)
}

// checking if password is valid
accountSchema.methods.validPassword = function (password) {
  return bcrypt.compareSync(password, this.local.password)
}

// create the model for users and expose it to our app
module.exports = mongoose.model('Account', accountSchema)

And finally my controller file AuthenticationController.js

const Account = require('../models/Account.js')
// var bodyParser = require('body-parser')

module.exports = {
  register (req, res) {
    Account.findOne({email: req.body.id}, function (err, account) {
      if (err) {
        console.log('Could not regster user')
        throw err
      }
      if (account) {
        console.log('account already exists')
      } else {
        Account.insertOne({email: req.body.email, password: req.body.password}, function (err, res) {
          if (err) {
            console.log('could not insert')
            throw err
          }
          console.log('inserted account')
          Account.close()
        })
      }
    })
  }
}

I am getting an error in my AuthenticationController file when I call Account.insertOne function.

I get the error that

TypeError: Account.insertOne is not a function

Now several of the posts here on stack have advised that I make sure that I am exporting the model from my model class, which I am doing, and that would fix this issue. Its weird because the findOne method seems to be fine, but when I call the insertOne i get an issue.

Am I missing something here?

A Mongoose model doesn't have an insertOne method. Use the create method instead:

Account.create({email: req.body.email, password: req.body.password}, function (err, doc) {
