Answer 1

According to the mongo document, we need to change the connection as bellow,

The legacy operation
MongoClient.connect('mongodb://localhost:27017/test', (err, db) => {
    // Database returned
});

is replaced with
MongoClient.connect('mongodb://localhost:27017/test', (err, client) => {
    // Client returned
    var db = client.db('test');
});

Don't need to downgrade the mongo version :)
