Heroku build successfull, but application error

I am trying to deploy an app which has a node backend and a react front end. I am using heroku and my code is below. It says there is an error with mongo, I tried re installing my node modules. I dont have much experience with heroku so any input would be great. Thanks in advance. In server.js - 

if (process.env.NODE_ENV === "production") {
  app.use(express.static("client/build"));

  app.get("*", (req, res) => {
    res.sendFile(path.resolve(__dirname, "client", "build", "index.html"));
  });
}

In package.json - 

{
  "author": "Spotify",
  "name": "web-api-auth-examples",
  "description": "Basic examples of the Spotify authorization flows through OAuth 2",
  "main": "server.js",
  "scripts": {
    "start": "node server.js",
    "client": "npm start --prefix client",
    "heroku-postbuild": "NPM_CONFIG_PRODUCTION=false npm install --prefix client && npm run build --prefix client"
  },
  "version": "0.0.2",
  "dependencies": {
    "bcryptjs": "^2.4.3",
    "body-parser": "^1.18.3",
    "cors": "^2.8.4",
    "dateformat": "^3.0.3",
    "express": "~4.16.0",
    "jsonwebtoken": "^8.3.0",
    "multer": "^1.3.1",
    "passport": "^0.4.0",
    "passport-jwt": "^4.0.0",
    "querystring": "~0.2.0",
    "request": "~2.83.0",
    "request-promise": "^4.2.2",
    "validator": "^10.4.0"
  }
}

The heroku log -

What I understand From your error and given package.json is that you are using mongoose somewhere in your application but mongoose is actually not installed.

Install mongoose to resolve the issue

npm install -s mongoose
