MongoParseError: options useCreateIndex, useFindAndModify are not supported

Question

I tried to run it and it said an error like the title. and this is my code:

const URI = process.env.MONGODB_URL;

mongoose.connect(URI, {
   useCreateIndex: true, 
   useFindAndModify: false, 
   useNewUrlParser: true, 
   useUnifiedTopology: true 
}, err => {
   if(err) throw err;
   console.log('Connected to MongoDB!!!')
})

I set the MONGODB_URL in .env :

MONGODB_URL = mongodb+srv://username:<password>@cluster0.accdl.mongodb.net/website?retryWrites=true&w=majority

How to fix it?

Check the docs for the version of Mongoose you are using, it should list the supported options. — Joe, Aug 28 '21 at 01:19
if I'm not wrong, the version of mongoose you're talking about is the same as the version of mongoose that I install using npm I mongoose? — viiii, Aug 28 '21 at 03:59

From the Mongoose 6.0 docs:

useNewUrlParser, useUnifiedTopology, useFindAndModify, and useCreateIndex are no longer supported options. Mongoose 6 always behaves as if useNewUrlParser, useUnifiedTopology, and useCreateIndex are true, and useFindAndModify is false. Please remove these options from your code.

Are these options totally removed or replace with other code?? – viiii Aug 28 '21 at 12:48

This answer from @Joe should be the accepted answer, since it report the documentation. A merge between this and the already accepted answer could be the best answer. – Daniele Tentoni Sep 07 '21 at 22:28
This is the winning answer if you're coming from 4.x/5.x ➡️ 6.x. You also need to change the deprecated `update`, `remove`, and `count` methods to the new ones. – Matt Lo Jan 30 '22 at 21:25

Same problem was with me but if you remove useCreateIndex, useFindAndModify it will solve the problem just write :

const URI = process.env.MONGODB_URL;

mongoose.connect(URI, {

useNewUrlParser: true, 

useUnifiedTopology: true 

}, err => {
if(err) throw err;
console.log('Connected to MongoDB!!!')
});

It worked for me.

The error is because of the new version of the mongoose i.e version 6.0.6.

As the documentation says:

No More Deprecation Warning Options

useNewUrlParser, useUnifiedTopology, useFindAndModify, and useCreateIndex are no longer supported options. Mongoose 6 always behaves as if useNewUrlParser, useUnifiedTopology, and useCreateIndex are true, and useFindAndModify is false. Please remove these options from your code.

Also, there are some major changes in the new version.

For more info visit https://mongoosejs.com/docs/migrating_to_6.html#no-more-deprecation-warning-options

import mongoose from 'mongoose';
    
    const db = process.env.MONGOURI;
    
    const connectDB = async () => {
      try {
        console.log(db);
        await mongoose.connect(`${db}`, {
          useNewUrlParser: true,
          useUnifiedTopology: true,
        });
        console.log('MongoDB connected');
      } catch (error) {
        console.log(error.message);
        process.exit(1);
      }
    };
    
    
    export default connectDB;

Use this to check your database connection:

const mongoose = require("mongoose");
const url = ... /* path of your db */;

//to connect or create our database
mongoose.connect(url, { useUnifiedTopology : true, useNewUrlParser : true , }).then(() => {
   console.log("Connection successfull");
}).catch((e) => console.log("No connection"))

basically, just remove that object and you'll be fine:)

I experienced same thing, all i did was to just omit both (useFindAndModify: false) and (useCreateIndex), the reason being that my mongoose version never supported any of this..

Sure this will work for you.

The asPromise() Method for Connections Mongoose connections are no longer thenable. This means that await mongoose.createConnection(uri) no longer waits for Mongoose to connect. Use mongoose.createConnection(uri).asPromise() instead.

// The below no longer works in Mongoose 6

await mongoose.createConnection(uri);

// Do this instead

 await mongoose.createConnection(uri).asPromise();

I have faced the same error the new mongoose version does already have these options by default for you so all you need to do is to remove these options and it will work perfectly.
