I'm trying to deploy my node.js app to heroku. I did everything as necessary, but i am getting error like this.

I tried to do this:

git push heroku master:main

Here is my package.json:

{
  "name": "languagelearningapp",
  "engines" : { "node" : "16.3.0" },
  "version": "1.0.0",
  "description": "",
  "main": "app.js",
  "scripts": {
    "start": "node app.js"
  },
  "author": "",
  "license": "ISC",
  "dependencies": {
    "basic-auth": "^2.0.1",
    "bcrypt": "^3.0.2",
    "bcryptjs": "^2.4.3",
    "body-parser": "^1.18.3",
    "callback": "0.0.1",
    "express": "^4.16.4",
    "fcm-node": "^1.3.0",
    "fcm-notification": "^2.0.0",
    "firebase-admin": "^6.2.0",
    "jsonwebtoken": "^8.3.0",
    "mysql": "^2.16.0",
    "nodemon": "^1.18.5",
    "sendotp": "^1.2.9"
  }
}

But it did not help. I also tried adding node modules to .gitignore, but it didn't work. In particular, I tried switching to a different branch, which did not work well.

PLease help me.

Look at the error. It says that npm ERR! 404 'har-validator@https://registry.npmjs.org/har-validator/-/har-validator-5.1.2.tgz' is not in the npm registry. If you look up har-validator on npm here, you can see that the package is deprecated — Samathingamajig

Have a look here, it was a GitHub issue raised which also had a problem with har-validator being deprecated. One solution proposed stated that you would start by upgrading the HLS plugin to remove the dependency on request which brings in har-validator, but mind the fact that they used ArtilleryIO. — Alex

what's the version of node you are using on your local dev machine ? — WaLid LamRaoui

It appears to me that you need to DOWNGRADE node to the LTS version on your local machine (use nvm for that), then basically reconfigure your project to use the LTS version : delete package.json and package-lock.json, delete node_modules folder then run npm init and install the dependencies you're using like bcrypt etc ..

After that you need to edit your new package.json and tell heroku to use LTS version also by adding this :

"engines": {
    "node": "14.x" 
  },

your package.json should look something like this :

{
  "name": "languagelearningapp",
  "engines" : { "node" : "14.x" },
  "version": "1.0.0",
  "description": "",
  "main": "app.js",
  "scripts": {
    "start": "node app.js"
  },
  "author": "",
  "license": "ISC",
  "dependencies": {
    // your project dependencies 
  }
}

i know i will come back for this later but this is what i would try first if i get the same issue.
