Heroku production deployment

[eman1000]

I deployed the app to heroku saving dist folder but am just getting a blank screen with this error in the console

web: node bin/server

bin/server
const express = require('express')
const path = require('path')
const PORT = process.env.PORT || 5000

express()
  .get('*', function(req, res) {  
    res.sendFile(path.join(__dirname, '../dist/index.html'));
  })
  .listen(PORT, () => console.log(`Listening on ${ PORT }`))
