When trying to connect to a server that is offline it is throwing a unhandled error instead of it being caught in the promise.catch.
import { MongoClient } from "mongodb"; // Connection URL const url = "<<PUT_URL_HERE>>"; const connect = async () => { const client = new MongoClient(url, { useNewUrlParser: true, useUnifiedTopology: true }); await client.connect(); await client.close(); }; connect().then(() => console.log("ALL DONE")).catch((err) => console.error(err));

How I came across this was when using Mongoose, if mongo server instance wne don't, it was crashing the process, instead of mongoose trying to reconnect. After narrowing it down it looks to be the Mongo driver that is causing it.
