I am trying to deploy my Node.js ES6 modules-based application to Heroku, it works fine locally with npm start and also when I run heroku local web but unfortunately in the deployment it throws the error attached in the screenshot.

This is how my package.json looks like.

{
  "name": "",
  "private": true,
  "type": "module",
  "engines": {
    "node": "12.6.0"
  },
  "scripts": {
    "start": "node --experimental-modules index.js",
  },
  "dependencies": {
    ...

  },
  "devDependencies": {
    ...
  }
}

I have also tried by upgrading Node to 13.2.0 as suggested in this thread https://stackoverflow.com/a/59399717/5763627, but nothing changes with Heroku.

Please give a [mre]. – jonrsharpe Mar 08 '20 at 12:11
its a deployment issue could you please let me know how can I give minimal reproducible example here? @jonrsharpe. – Divyanshu Rawat Mar 08 '20 at 12:30
Would need to see your `config.js` file. That is where the error is being raised. Perhaps it's a build item and the build on your local machine is different from the config file that is built by heroku on your server – elight Mar 09 '20 at 19:03

@elightI fixed it it was something with Heroku deployment cache. although thanks :) – Divyanshu Rawat Mar 10 '20 at 09:25
