I tried multiple ways to fix this issue (add/ modify Procfile, modify package.json...) but still not able to fix it. It would be appreciated if you can give me a hand, thanks in advance.

Here is the Heroku log:

Here is Github:

add/ modify Procfile, modify package.json

After set Procfile to web: npm start, received new Heroku logs:

  • It seems you have a typo. Your file is `backend/server.js` yet your `Procfile` is `node servers.js` (notice the plural). – acdcjunior Nov 03 '22 at 03:39

Try running the script you have defined in your package.json from your Procfile:

web: npm start

I noticed that you defined certain versions for Heroku to run for node and npm, are those the same versions you are running locally? I have had luck in the past by setting these greater than or equal to the version I wanted:

  "engines": {
    "node": ">=14.17.4"
    "npm": ">=6.14.14"
   }

  • Hi Lexabu, thanks for your answer, I tried your suggestion for "web: npm start" and now received new Heroku logs, let me find out how to post it here in StackOverFlow. Just updated on my post. – Xuan Khang Huynh Nov 03 '22 at 04:02

    In production or in deployment you shouldn't be using nodemon. – lexabu Nov 03 '22 at 04:32
