MongoDB Node.js issue with "Callbacks are deprecated"

Hello I have issue with MongoDB code, it make some methods like this (image below):
enter image description here

`

var MongoClient = require('mongodb').MongoClient;
var url = "mongodb://localhost:27017/";

MongoClient.connect(url, { useUnifiedTopology: true }, function (err, db) {
  if (err) throw err;
  var dbo = db.db("mydb");
  var mysort = { name: 1 };
  dbo.collection("customers").find().sort(mysort).toArray(function (err, result) {
    if (err) throw err;
    console.log(result);
    db.close();
  });
});

`

and when I try read error, it say:

(method) MongoClient.connect(url: string, callback: Callback): void (+3 overloads)
@deprecated — Callbacks are deprecated and will be removed in the next major version. See mongodb-legacy for migration assistance

The signature ‘(url: string, callback: Callback): void’ of ‘MongoClient.connect’ is deprecated.ts(6387)
mongodb.d.ts(4733, 9): The declaration was marked as deprecated here.
No quick fixes available

I tried reinstall it, or install older version and still same, I do connection same like in documentation.

Tried add (url,{ useUnifiedTopology: true }, and still same

Someone know what can be issue?

    Try version 4.0.0

    const MongoClient = require('mongodb').MongoClient;

// Connect to the MongoDB server
MongoClient.connect('mongodb://localhost:27017/', function(err, client) {
  if (err) throw err;

  // Get the sample database
  const db = client.db('sample');

  // Get the collection
  const collection = db.collection('test');

  // Insert a document
  collection.insertOne({ name: 'John', age: 30 }, function(err, result) {
    if (err) throw err;

    console.log(result);

    // Close the connection
    client.close();
  });
});

    Let me know if you still have the same error .

    Step 1: Replace your current version with the following:

    Step 2: Require this into your project

    const mongoClient = require('mongodb-legacy').MongoClient
