JawsDB error connecting with Heroku - mysql

Question

I tried to push my project to heroku and connect jawsdb with the application. I input jawsdb info into my server.js and updated it then pushed to heroku. But I'm getting this erorr and the application wont load. I think it has something to do with the way I'm setting up the database.
I am receiving the following "Access denied for user" error:
https://ibb.co/giRO5m
this is my code: server.js
var express = require('express');
var bodyParser = require('body-parser');
var mysql = require('mysql');
var logger = require('morgan');
var request = require('request');
var cheerio = require('cheerio');
var methodOverride = require('method-override')
var fs = require("fs");
var hbs = require('hbs');
// Set up Express
var app = express();
var router = express.Router();
//handlebars
var handlebars = require('express-handlebars').create({defaultLayout:'main'});
app.engine('handlebars', handlebars.engine);
app.set('view engine', 'handlebars');
// override with POST having ?_method=DELETE
app.use(methodOverride('_method'))
// Set up Mysql
var con = mysql.createConnection({
host: "t89yihg12rw77y6f.cbetxkdyhwsb.us-east-1.rds.amazonaws.com",
port: 3306,
user: "swvr0i1j9ny720mk",
password: "e3lzkqag4dmeqhup"
});
//conecting to mysql
con.connect(function(err) {
if (err) throw err;
console.log("Database connected to the matrix..");
});
con.query('CREATE DATABASE IF NOT EXISTS warehouse', function (err) {
if (err) throw err;
con.query('USE warehouse', function (err) {
if (err) throw err;
con.query('CREATE TABLE IF NOT EXISTS storage('
+ 'id INT NOT NULL AUTO_INCREMENT,'
+ 'PRIMARY KEY(id),'
+ 'link VARCHAR(255),'
+ 'item VARCHAR(255),'
+ 'stock VARCHAR(255)'
+ ')', function (err) {
if (err) throw err;
});
});
});
// Parse application/x-www-form-urlencoded
app.use(logger('dev'));
app.use(bodyParser.urlencoded({ extended: true }));
app.use(bodyParser.json());
// Serve static content for the app from the "public" directory in the application directory.
app.use(express.static(__dirname + '/public'));
//prints database to page
app.get('/index', function(req,res) {
con.query('SELECT * FROM storage;', function(err, data) {
if (err) throw err;
//test it
//console.log('The solution is: ', data);
//test it
//res.send(data);
res.render('index', {storage : data});
});
});
//delete data entry
app.delete('/delete', function(req,res){
con.query('DELETE FROM storage WHERE id = ?', [req.body.id], function(err, result) {
if (err) throw err;
res.redirect('/index');
});
});
// Open Server
app.listen(process.env.PORT || 3000, function(){
console.log("Express server listening on port %d in %s mode", this.address().port, app.settings.env);
});

JawsDB does not let you choose the database name or create a new database name. Instead, you will need to connect via a workbench tool and see what the database name they have given you is (for example, the below show my database name JawsDB assigned).
Then, use this database in your code instead of the one you named "warehouse." For example, if I were to do this with the schema JawsDB named for me, I would use 'jdjkhrjps1cgj89h'
con.query('USE jdjkhrjps1cgj89h', function (err) {
if (err) throw err;
con.query('CREATE TABLE IF NOT EXISTS storage('
+ 'id INT NOT NULL AUTO_INCREMENT,'
+ 'PRIMARY KEY(id),'
+ 'link VARCHAR(255),'
+ 'item VARCHAR(255),'
+ 'stock VARCHAR(255)'
+ ')', function (err) {
if (err) throw err;
});
});
