[SandboxUnhandledError] Cannot read properties of undefined (reading 'n')

I’m getting an error when I try to verify a Gmail in MongoDB

function verify (email, callback) {
  const MongoClient = require('mongodb@4.1.0').MongoClient;
  const client = new MongoClient('mongodb+srv://<usernam>:<password>@cluster0.dcaauoo.mongodb.net/?retryWrites=true&w=majority');

  client.connect(function (err) {
    if (err) return callback(err);

    const db = client.db('db-name');
    const users = db.collection('users');
    const query = { email: email, email_verified: false };

    users.update(query, { $set: { email_verified: true } }, function (err, result) {

      if (err) return callback(err);
      callback(null, result.result.n > 0);

In real code user and password have.
