javascript - Unsupported OP_QUERY command: insert. The client driver may require an upgrade - Stack Overflow

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();

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.

• Did you try the update as advised by the error message? – Wernfried Domscheit Commented Dec 2, 2022 at 20:42
• you mean upgrade to nodejs? yes my current nodejs version is(18.12.1) @Wernfried Domscheit – Coder1989 Commented Dec 2, 2022 at 20:52
• The MongoDB driver: npmjs./package/mongodb – Wernfried Domscheit Commented Dec 2, 2022 at 22:16
• Frustratingly, the error links to this page: https://www.mongodb./docs/v6.0/release-notes/6.0-patibility/#legacy-opcodes-removed but does not include HOW to upgrade, but has a section on Downgrade Considerations. A bit of an oversight there I think. $npm install mongodb updated my version with no visible side effects. – Rin and Len Commented May 23, 2023 at 13:05
• This question is similar to: "Unsupported OP_QUERY mand: insert" in Elixir project when trying to insert into Mongo DB. If you believe it’s different, please edit the question, make it clear how it’s different and/or how the answers on that question are not helpful for your problem. – ray Commented Sep 29, 2024 at 17:25

In my case the problem was an old version of the connect-mongodb-session npm package. Check if you use it.

I fixed the error by upgrading connect-mongodb-session version 2.0.6 to the latest 3.1.1.

I have MongoDB 6.0.6 installed.

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 remended for patibility with the code snippet you shared.

The error is showing because of two reasons either mongoose version has bee old or it has not been installed yet . try installing mongoose again

npm i mongoose

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

If your using Windows:

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

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

Try installing mongoose again

npm i mongoose

This is caused due to the usage of outdated version of packages.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

1. Download latest version of node

   nvm install 18

   nvm use 18

2. Upgrade mongoose to latest version

   npm i mongoose@latest

3. 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
