Unsupported OP_QUERY command: insert. The client driver may require an upgrade

I stuck up with this error for the last two days. I am new to node and MongoDB and because of this error, I could not proceed further.

Here is my code for reference.

const express = require('express');
//const app = express();

const mongoose = require('mongoose');


mongoose.connect('mongodb://localhost:27017/playground')
.then(() => console.log('connected to mongoDB'))
.catch(err => console.log('could not connect')) 

const courseSchema = new mongoose.Schema({
    name: String,
    author: String,
    tags: [String],
    date: { type: Date, default: Date.now },
    isPublished: Boolean
});

const Course = mongoose.model('course', courseSchema);

async function createCourse(){
    const course = new Course({
        name: 'Angular Course',
        author: 'Node Learner',
        tags: [ 'Angular', 'backend'],
        isPublished: true
    });

    const result = await course.save();
    console.log(result);
}
createCourse();

  code: 352,
  codeName: 'UnsupportedOpQueryCommand'

I browsed about this error and it always tells me to the client driver may require an upgrade.

My node.js version is the current stable version - 18.12.1.
My npm version is 8.19.2

I also checked my network connection and tried VPN too.

This is caused due to the usage of outdated version of packages. Use the following commands to resolve this error

Download latest version of node

nvm install 18

nvm use 18
Upgrade mongoose to latest version

npm i mongoose@latest
Get the latest version of mongodb here

Note: Make sure to update your path in environmental variables to match the bin folder of newly downloaded MongoDB version

If your using Windows:

If you are using newer version like I did (v7.0.2), You should consider downgrading your MongoDB version to a compatible one, like 3.6.23
Install [email protected]
Remember to update path in Environment variables.
Run mongod in command prompt, and if it doesn't start, try again after restarting windows.
if in command prompt, you see waiting for connections, you are good to go

This is my exprience and how I solved it. Hope it helps

I think your node is upgraded so try to use 127.0.0.1 instead of localhost in the connection string

To run the provided code successfully, please ensure that you have MongoDB version 4.4 installed and the Mongoose library version 5.0.1. These specific versions are recommended for compatibility with the code snippet you shared.
