Create droplet with User Data

Hi, I getting started with DigitalOcean V2 API. When I tried create droplet with user data via API, server is created without executed my code. The same code when I did pasted in the browser and created droplet working properly.

This is my code:

$droplet->create('the-name', 
		'nyc1', 
		'512mb', 
		'ubuntu-16-04-x64', 
		false, 
		false, 
		false, 
		array($key),
		'
#!/bin/bash
			
sudo apt-get update
debconf-set-selections <<< "postfix postfix/mailname string domain.com"
debconf-set-selections <<< "postfix postfix/main_mailer_type string \'Internet Site\'"
apt-get install -y postfix
sudo postconf -e \'home_mailbox= Maildir/\'
sudo postconf -e \'virtual_alias_maps= hash:/etc/postfix/virtual\'

printf "kontakt@e-cleaner.net.pl root" > /etc/postfix/virtual
sudo postmap /etc/postfix/virtual
sudo systemctl restart postfix
sudo apt-get update
sudo ufw allow Postfix
echo \'export MAIL=~/Maildir\' | sudo tee -a /etc/bash.bashrc | sudo tee -a /etc/profile.d/mail.sh
sudo apt-get install s-nail
echo \'init\' | mail -s \'init\' -Snorecord

What is the reason of my problem?
