Side note: I've used this same method for deployment about 3 times and now all of the sudden it's not working... Makes me think that something just updated with heroku??? IDK

Trying to push my MERN Stack application to heroku but I'm getting an error, here is my package.json file:

```
{
  "name": "jordanwebsite",
  "version": "1.0.0",
  "description": "",
  "main": "server.js",
  "scripts": {
    "start": "node server.js",

    "client-install": "npm install --prefix client",
    "client": "npm start --prefix client",
    "dev": "concurrently \"npm run server\" \"npm run\tclient\"",
    "heroku-postbuild": "cd client && NPM_CONFIG_PRODUCTION=false npm install && npm run build"
  },
  "author": "Jordan Harris",
  "license": "ISC",
  "dependencies": {
    "axios": "^0.18.0",

    "concurrently": "^4.1.0",
    "express": "^4.16.4",
    "nodemon": "^1.18.9"
  }
}

```

Here are the logs:
