8Cant deploy Nodejs server in Heroku : 'Error: Cannot find module 'getStream''

My project seems to have no issues when running locally, but when I try to deploy it in heroku and open the app it gives me an application error. I tried checking the logs in heroku and this is what I get.

I have tried checking for missing scripts, changing the Port to process.env.PORT, heroku repo:reset, deleting the git file and starting a new git init and even deleting the node_modules folder and running npm install. A similar app I tried hosting in heroku seems to run with no problems, the difference being this one has a mysql dependency and the heroku app has a clearDB plugin. The 'getstream' version is '8.0.1' (the one that runs without problems is '8.0.0' could that be the issue?).

Found the problem in the auth.js file: I had written const {connect} = require('getStream'); instead of const {connect} = require('getstream');. So I guess it was due to naming conventions in a way. #Chris ty, that first question was right on the money.

How to fix this error
Thank you in advance

I'm assuming you are using mongodB atlas. You need to whitelist your IP address. To do that, head over to your network access tab, and include an IP address 0.0.0.0/0. This is a wild card IP address that would allow all IP addresses with the correct credentials to access your DB.
As such:
Note: This whitelists all IP addresses. It's alright when testing. But when going into production, you might want to whitelist only IP addresses that should have access to the cluster...for security purposes.

Querying a mongo DB causes Heroku timeout?

I'm using a simple node app with an express server and attempting to deploy it to heroku and a single query to the database causes my app to crash with an H13 error after about 10 seconds. The error says it closed without response.

The entire code can be found here.
or here with omitted commented out code:
server.get('/:state/:classification/:className', async (req, res) => {
let className = req.params.className.replaceAll('-', ' ');
className = className.replaceAll('/', ' ');
const { url } = await classificationsModel.findOne(
{
name: className.toLowerCase(),
associatedState: req.params.state.toUpperCase(),
},
{ url: 1, _id: 0 }
);
console.log(url);
res.json('hello world');
teamList = [];
});
Again locally this is produced in the console and 'hello world' is returned as json. Why is it different on heroku and how can I fix it?

I'm trying to deploy my first MongoDB, Express, websockets app to Heroku and I can't get it to connect

**
I've added a Procfile, added ObjectRocket addon, and created a DB there
heres whats in the Procfile
**
```
web: node server.js
```
Here's whats in the .env file
*
```
ORMONGO_URL='mongodb://iad2-c13-0.mongo.objectrocket.com:53577'
ORMONGO_REGION=IAD
ORMONGO_RS_URL='mongodb://iad2-c13-0.mongo.objectrocket.com:53577,iad2-c13-
2.mongo.objectrocket.com:53577,iad2-c13-1.mongo.objectrocket.com:53577/?
replicaSet=5df3e347a4384bf8968b430ec021a64f'
PORT = 8000
```
Here's my server.js where I try to connect to the ObjectRocket addon database:
*
```
*
WEB/HTTP SERVER
*
```
const mongodb = require("mongodb");
const bodyParser = require("body-parser");
const session = require("express-session");
const MongoStore = require("connect-mongo")(session);
const path = require("path");
const express = require("express");
const app = express();
const MongoClient = require("mongodb").MongoClient;
```
Here I try to create the connection string
```
var username = "james";
var password = "websockets";
var hosts =
"iad2-c13-0.mongo.objectrocket.com:53577,iad2-c13-2.mongo.objectrocket.com:53577,iad2-c13-
1.mongo.objectrocket.com:53577";
var database = "websockets";
var options = "?replicaSet=5df3e347a4384bf8968b430ec021a64f";
var connectionString =
"mongodb://" +
username +
":" +
password +
"#" +
hosts +
"/" +
database +
options;
Here I set express for pug and files
app.use("/public", express.static(__dirname + "/public"));
app.set("view engine", "pug");
app.use(
bodyParser.urlencoded({
extended: true,
})
);
```
First attempt to connect to add user to DB
```
app.get("/", (request, response, next) => {
response.render("signup");
});
app.post("/signup", (request, response, next) => {
request.body.name;
request.body.email;
request.body.password;
mongodb.MongoClient.connect(connectionString, (error, client) => {
if (error) {
console.log(error);
response.redirect("/signup");
} else {
const db = client.db("websockets");
db.collection("users", (error, collection) => {
collection.insertOne(
{
name: request.body.name,
email: request.body.email,
password: request.body.password,
},
(error, result) => {
if (error) {
response.redirect("/signup");
}
}
);
});
response.redirect("/login");
}
});
});
```
heres the error log

I checked my mongodb atlas cluster and my ip address is in whitelist. Also, i tried to set network access to 0.0.0.0/0 but its didn't worked too...
By the way, everything is works perfectly in my local address (8080).

I fixed it.
I added this things in my code;
mongoose.Promise = global.Promise;
...
const PORT = process.env.PORT || 8080;
const CONNECTION_URI = process.env.MONGODB_URI || 'mongodb+srv://learnBlogAdmin:learnBlogAdminsPowsyetmiş22a#learningcluster-izdfm.mongodb.net/personalblog?retryWrites=true&w=majority';
...
run()
.then(() => {
console.log("IT WORKS");
})
.catch((err) => {
console.log(err);
throw err;
})
And its worked.
