Unable to connect to MongoDB Cluster deployed on MongoDB Cloud using Node.js

[Sandeep_Chatterjee]

Hi Everyone,

I am new to MongoDB and Node.js. I am following the MongoDB documentation and am currently unable to connect to the MongoDB Cluster using Node.js, but it appears to be functioning normally as I am able to establish a connection using the Mongo Shell without any issues.

The following works fine when I run from a terminaL

mongosh "mongodb+srv://my-default-cluster.nopctvg.mongodb.net/" --apiVersion 1 --username sandeepc
Enter password: ***********
Current Mongosh Log ID:	650b432e52a027b381779cdd
Connecting to:		mongodb+srv://<credentials>@my-default-cluster.nopctvg.mongodb.net/?appName=mongosh+2.0.1
Using MongoDB:		6.0.10 (API Version 1)
Using Mongosh:		2.0.1

For mongosh info see: https://docs.mongodb.com/mongodb-shell/
Atlas atlas-cjxqji-shard-0 [primary] test>

However, when I run the following code, it gives me an error. The password enclosed within the parentheses is replaced by the actual password.

Code

const { MongoClient, ServerApiVersion } = require('mongodb');
const uri = "mongodb+srv://sandeepc:<password>@my-default-cluster.nopctvg.mongodb.net/?retryWrites=true&w=majority";

// Create a MongoClient with a MongoClientOptions object to set the Stable API version
const client = new MongoClient(uri, {
  serverApi: {
    version: ServerApiVersion.v1,
    strict: true,
    deprecationErrors: true,
  }
});

async function run() {
  try {
    // Connect the client to the server	(optional starting in v4.7)
    await client.connect();
    // Send a ping to confirm a successful connection
    await client.db("admin").command({ ping: 1 });
    console.log("Pinged your deployment. You successfully connected to MongoDB!");
  } finally {
    // Ensures that the client will close when you finish/error
    await client.close();
  }
}
run().catch(console.dir);

Error:

/foo/node_modules/mongodb/lib/admin.js:62
            session: options?.session,
                             ^

I just ran npm init followed by npm install mongodb and node connect.js it gave me the above error.

Not sure what am I doing wrong here.

Hello, welcome to the MongoDB community.

I’m not very knowledgeable about nodeJS, but from the examples I saw, they import the client and then you put it as a variable, is it the same thing? Example for finding documents:

import {MongoClient} from "mongodb";

// Replace the uri string with the connection string from your MongoDB deployment.
const uri = "<connection string uri>";

const client = new MongoClient(uri);

asynchronous function run() {
  to try {
    
    // Gets the database and collection on which to perform the operation
    const database = client.db("sample_mflix");
    const movies = database.collection("movies");

    // Query for a film titled 'The Room'
    const query = {title: "The Room"};

    const options = {
      // Sorts matching documents in descending order by rank
      sort: { "imdb.rating": -1 },
      // Includes only the `title` and `imdb` fields in the returned document
      projection: {_id: 0, title: 1, imdb: 1},
    };

    //Run query
    const movie = wait for movies.findOne(query, options);

    // Print the document returned by findOne()
    console.log(movie);
  } finally {
    wait client.close();
  }
}
run().catch(console.dir);

Hi Samuel,

I am using the same code provided here in nodejs-quickstart but it just throws the error mentioned in the original post.

I can connect fine to my cluster from mongo shell using the below, but not from nodejs.

mongosh “mongodb+srv://my-default-cluster.nopctvg.mongodb.net/” --apiVersion 1 --username sandeepc

This error is commonly a syntax problem from the driver vs the Node.JS version.

• Make sure you have the most up to date drivers/node.js versions.
• Double check for tokens. If your version of Node.JS is less that 14, get it to 14 or chaining isn’t supported.

It’s also possible you’re just using the wrong password…

Thank you, Brock. Updating the node version to the latest one v20.7.0 fixed the problem. Cheers.
