MongoNetworkTimeoutError crashes my process even though I catch the error with connection.on( 'error', () => {} ).
The error event is triggered while the server isn't reachable, but the process is crashed.

Steps to Reproduce

const connection = mongoose.createConnection( uri, options );
connection.on( 'error', e => { console.log( e ) } );

Expected Behavior

No response

Need more details. What's your connection string look like. What else are you doing?

[LvChengbin]

I want to say that when there's a connection error, The error should be catchable instead of crashing the process, without asking why the connection timed out.

t looks like the following script throws an uncaught error, we're investigating

'use strict';

const mongoose = require('mongoose');

const conn = mongoose.createConnection('mongodb://fail:27017/mongoose_test', { serverSelectionTimeoutMS: 1000 });
conn.on('error', err => console.log('Error hander', err));

In general, we would recommend handling errors using asPromise(), like const conn = await mongoose.createConnection(uri).asPromise() rather than relying on on('error'), but we'll fix this issue.
