Hey have you fixed this problem? Currently I am facing the similar problem

Hi I think I read something related Receive DEP0170 when connecting MongoDB Atlas with Node.js 20.3.1 - Stack Overflow, I think they’re saying it’s because of the numerous :, making node thinking it’s port numbers.

AMAN_Vijay · 2023-11-25T04:17:30.552Z

Facing the same issue,is there any solution for this?

Hung_Ngo · 2023-12-08T03:03:48.869Z

I have the same issue!

Emmanuel_Ibekwe · 2023-12-20T11:03:14.816Z

I keep getting the same erro while trying to deploy my node js project on render.com

~~Which version of the Node.js Driver are you using?~~ Ignore this, we found the info we needed (see below)

alexbevi · 2023-12-20T19:33:24.168Z

Note that after a bit of digging we’ve filed NODE-5802 for this issue. For anyone watching this thread the issue only affects 3.x of the driver (and any version of Mongoose that pins a 3.x version of the driver).

Upgrading to 4.x+ will address this warning.

Emmanuel_Ibekwe · 2023-12-21T11:25:27.181Z

Never mind. I was using a mongodb driver of version 2.x. I upgraded to 3.x and the issue was resolved. Thanks for the response.

saraEl · 2023-12-27T08:40:33.901Z

I encountered the same issue and resolved it it this way :
I uninstalled the mongoose and mongodb packages.
Afterward, I installed the latest version of mongoose using this command:

npm install mongoose@latest

Upon encountering this error:
“connection error: MongoParseError: options usecreateindex, usefindandmodify are not supported at parseOptions”.

I updated my mongoose connection method. Now, it looks like this:

mongoose.connect(dbUrl);

As a result, everything is now working well.

I wanted to add to the discussion for those who came to this thread after searching for a solution. I made the above updates to “mongoose” and was still getting the error message.

I forgot that I was also connecting using a MongoDB transport for Winston.

If you are using “winston-mongodb” don’t forget to add options:

winston.add(
  new winston.transports.MongoDB({
    db: 'mongodb://localhost/vidly',
    level: 'error',
    options: { useUnifiedTopology: true },
  })
);

Valerio_Maietta · 2024-01-06T15:13:55.593Z

I have a similar situation to yours:

winston.add(
  new winston.transports.MongoDB({
    level: 'info',
    db: process.env.DATABASE,
    collection: 'info_logs',
    options: {
      useUnifiedTopology: true,
    },
  })
);

But I had the error:
[DEP0170] DeprecationWarning: The URL mongodb://<USERNAME>:<PASSWORD>@ac-4hlp44x-shard-00-01.nqjamzn.mongodb.net:27017,ac-4hlp44x-shard-00-02.nqjamzn.mongodb.net:27017,ac-4hlp44x-shard-00-00.nqjamzn.mongodb.net:27017/<DATABASE>?authSource=admin&replicaSet=atlas-g8a2vr-shard-0&retryWrites=true&w=majority&ssl=true is invalid. Future versions of Node.js will throw an error.

Chris_Stromberg · 2024-01-07T03:18:49.422Z

Update to latest for Winston, MongoDb, Mongoose. Then run “npm ci” , this cleared everything up for me.

Bealu_Girma · 2024-01-22T11:44:10.712Z

i had the same problem this is caused by old version of mongoose

npm install mongoose@latest

Apuliba_Atawine · 2024-04-17T22:43:23.556Z

Had the same error when connecting loopback 4
Below is my configuration
const config = {
name: ‘mydatasource’,
connector: ‘mongodb’,
url: ‘mongodb+srv://username********@developing.cpd3inw.mongodb.net/todos’,
host: ‘’',
port: ‘’,
user: ‘’,
password: ‘’,
database: ‘testdb’,
useNewUrlParser: true
};

Erick_Pacheco · 2024-05-05T14:01:58.383Z

Hi everyone!

To solve this issue, first install the latest version of mongo by running: npm i mongo@latest
Then, remove the options passed to the MongoClient connect.

` const connection = await MongoClient.connect(mongoDBURL)````

(node:18412) [MONGODB DRIVER] Warning: useUnifiedTopology is a deprecated option: useUnifiedTopology has no effect since Node.js Driver version 4.0.0 and will be removed in the next major version

node : 20.16.0

How can solve it ?

Safwen_Saafi · 2024-08-19T11:17:43.558Z

did you install the mongodb driver ?
npm i mongodb

Sunny_Choudhary · 2025-03-19T11:36:11.243Z

Downgrading the node version from 22 to 14 worked for me

Ifeanyi_Omeata · 2025-06-29T06:25:55.787Z

just update mongoose and it well be solved
npm install mongoose@latest
