Yep, you can ignore this one for now. It’s just warning you that this will be an issue when you upgrade to the next major version.
A little more info from one of the driver engineers:
Db is no longer the place to listen to events, you should listen to your MongoClient instead like so:
const client = new MongoClient(…)
client.on(‘Event name I want to listen too’, () => {…})
await client.connect()The reason for this style is because by registering your listeners before connecting you can be sure that you’re able to capture every event that is triggered
