Node.js: Fail to deploy node.js application to heroku

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.

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.
