      1. What would you like to communicate to the user about this feature?
      2. Would you like the user to see examples of the syntax and/or executable code and its output?

      import { MongoClient } from 'mongodb';

const client = await MongoClient.connect('mongodb://localhost:27017/');
const result = await client.db('test').collection('test').aggregate([], { raw: true }).toArray();
console.log(result);
await client.close();

      works fine in 6.5.0, throws in 6.6.0

Node.js v20.13.1

      Use Case

      As a... driver user
      I want... the driver to not throw exceptions in normal usage
      So that... I can update to the latest patch release of the driver

      User Impact

      No idea. This was caught by Compass's tests.

      Dependencies

      Can work around this on our side, so N/A.
