shortenedURL - Problem deploying to heroku


My app works just fine locally but won’t deploy to heroku.

Any help would be greatly appreciated. There is a similar issue on the forum but involves mongodb. This is a bit outside the scope of FCC but if anyone has any experience with this issue, please help.

Error: Cannot find module ‘lodash/keys’

  • Something to do with the keys file, I suspect
  • keys is in root project directory/keys.js and it specified to be ignored by .gitignore file

I dont even use lodash in this app!!!

  • I installed and required lodash, lodash.keys, and mongodb just to see what it would do - nothing
    (im using mongoose and mLab and it works locally without installing mongodb)

const express = require('express');
const bodyParser = require('body-parser');
const cors = require('cors');
const path = require('path');
const mongoose = require('mongoose');
const { mongoURI } = require('./keys');
const routes = require('./routes/routes');

const app = express();
app.use(cors({ optionsSuccessStatus: 200 }));
app.use(bodyParser.urlencoded({ extended: true }));

app.get('*', (req, res) => {
  res.sendFile(path.resolve(__dirname, 'build', 'index.html'));

  .once('open', () => console.log('Connection Established'))
  .on('error', (error) => console.warn('Warning', error));

const PORT = process.env.PORT || 5000;

module.exports = app;
