I am trying to deploy my node app to Heroku.
I have added the MLab MongoDB add on and have set the config variable
$ heroku config
=== thevoyageapp Config Vars
MONGODB_URI: mongodb://heroku_f80ngvbz:btt04p7erog80#ds.mlab.com:11/herokgvbz
And have added the process.env.MONGODB_URI to my mongo connection
const mongoose = require('mongoose');
let url = process.env.MONGODB_URI || 'mongodb://localhost/trip';
mongoose.connect(url, { useMongoClient: true });
But I still get this error:

Any idea what could be the issue?
It is highly possible that you forget to whitelist the server IP to access MongoDB database. You can whitelist the IP at MongoDB Atlas.

When I start my project via Heroku I am getting an error saying that "app" is not defined. I have logged "app" and get data back so I do not know why this is happening. Has anyone had this issue before? Here are the errors and the code:

app.js:
const express = require("express");
const apiRouter = require("./routes/apiRouter");
const app = express();
const {
handlePsqlErrors,
handleServerErrors,
} = require("./errorHandlingFunctions/errorFunctions");
app.use(express.json());

console.log(app);
const { PORT = 9090 } = process.env;
app.listen(PORT, () => console.log(`Listening on port ${PORT}...`));
This is the error it gives me when I deploy to heroku
It is says that I should check the file "localScrape.js" on line 11 column 21.
I went and included a try/catch block to work my way around it but it is persistently giving me the same error could.

It seems like the connection to your db was refused. Make sure you are using the correct database account and that it has privileges.
Also make sure to whitelist your app from db.
You need to whitelist the following ips: 127.0.0.1 and localhost
this thread can possibly be of help: node.js mysql error: ECONNREFUSED
Yes, you need a MySQL DB running. The easiest way is to install Docker on your machine, and use the official MySQL container.
I've been trying to fix a heroku api but I keep getting an error which I cant fix. The app is not even running, it goes straight to the error. It was working until I recently made an update to the api.
The error is shown as

My server.js file has
const express = require('express')
const bodyParser = require('body-parser')
const cors = require('cors')
const app = express()
app.use(cors())
//const PORT = process.env.PORT || 3000;
app.listen(process.env.PORT || 3000,function(){
console.log('server has been started')
})
app.use(bodyParser.json({limit: "500mb"}));
app.use(bodyParser.urlencoded({limit: "500mb", extended: true, parameterLimit:50000}));
app.use('/api',require('./routes/api'))
The other files are just the api and the schema for mongodb.
Please help
I see that there is a bcrypt related error. Are you using different Node.js version on your local dev and your prod? If yes then try to ignore the package manager lock file yarn.lock or package-lock.json.
lock file usually "hold" version specific dependency, in some case package with native dependency like bcrypt can cause some issue.
I have script from CSgo roullete.when im try run it show me this error

Most likely your mysql server is not running, or running on a different port/interface.
