Heroku: Push rejected, failed to compile Node.js app-CodePudding

I used to push my local repo into Heroku without any issue, then I had to downgrade Node from 17.3.0 to 16.14.0, afterward I have been running into this error.

Error Log on Heroku:

This is my package.json:

{
  "dependencies": {
    "bcrypt": "^5.0.1",
    "body": "^5.1.0",
    "body-parser": "^1.19.1",
    "cors": "^2.8.5",
    "express": "^4.17.2",
    "express-validator": "^6.14.0",
    "jsonwebtoken": "^8.5.1",
    "mongodb": "^4.3.0",
    "mongoose": "^6.1.8",
    "morgan": "^1.10.0",

  "description": "To build the server-side component of a “movies” web application. The web application will provide users with access to information about different movies, directors, and genres.

  "version": "1.0.0",
  "main": "index.js",
  "keywords": [],
  "author": "",
  "license": "ISC"
}

And here is my package-lock.json under the voice "package":

"packages": {
    "": {
      "name": "movie",
      "version": "1.0.0",
      "license": "ISC",

        "cors": "^2.8.5",
        "express": "^4.17.2",
        "express-validator": "^6.14.0",
        "jsonwebtoken": "^8.5.1",
        "mongodb": "^4.3.0",
        "mongoose": "^6.1.8",
        "morgan": "^1.10.0",
        "node": "^17.3.1",
        "parsr": "^0.0.1",
        "passport": "^0.5.2",
        "passport-jwt": "^4.0.0",
        "passport-local": "^1.0.0",
        "sequelize": "^6.12.5",
        "uuid": "^8.3.2"
      }

As you can see there are two different versions of Node reported...

.gitignore has already:

node_modules

What is the problem, and how can I fix it?

CodePudding user response：

Ran into this one a few times ago. If your local version of node.js is not Heroku one, you should add theses lines into you package.json:

"engines": {
  "node": "your_node_version" // in my case it was 14.x
},

CodePudding user response：

In the end, I used a version from my Repo that worked fine and that I was able to push on Heroku. I applied what I need to change and uploaded it again without issues.
