Download from FTP with Node JS - node.js

Question

I need help downloading more than one file from a remote FTP using Node js, the code is the following.
const FTPClient = require('ftp');
let ftp_client = new FTPClient();
const fs = require("fs");
let ftpConfig = {
host: "remoteHost",
port: 21,
user: 'username',
password: 'password',
}
//create a connection to ftp server
ftp_client.connect(ftpConfig);
ftp_client.on('ready', function() {
ftp_client.get('/file1.csv', function(err, stream) {
if (err) throw err;
//stream.once('close', function() { ftp_client.end(); });
stream.pipe(fs.createWriteStream('file1.csv'));
});
ftp_client.get('/dir/file2.dat', function(err, stream) {
if (err) throw err;
//stream.once('close', function() { ftp_client.end(); });
stream.pipe(fs.createWriteStream('file2.dat'));
});
ftp_client.get('/dir/file3.dat', function(err, stream) {
if (err) throw err;
stream.once('close', function() { ftp_client.end(); });
stream.pipe(fs.createWriteStream('file3.dat'));
});
});
And the error
Error: Unable to make data connection

at writeOrBuffer (_stream_writable.js:387:5)
at Parser.Writable.write (_stream_writable.js:318:11)
It is already downloading the 3 files, but also showing that error, so how can I correct this to do it in a safer way?
I also would like to add a console log while the process is downloading each file.
Thanks!
