Weird null

[ocean holly]

Hi. When im using this:

public class ButtonEvent implements Listener
{
    @EventHandler
    public void onButton(PlayerInteractEvent e)
    {
        if (e.getClickedBlock().getType() == Material.STONE_BUTTON)
        {
            Button button = ((Button) e.getClickedBlock().getState().getData());
            Block block = e.getClickedBlock().getRelative(button.getAttachedFace());

            if (block.getType().equals(Material.SPONGE))
            {
                RandomTeleportUtil.randomTeleport(e.getPlayer());
            }
        }
    }
}

It works with no problem, but, it gives a null error: https://www.toptal.com/developers/hastebin/erijojekaq.rb
It shows line 16, the first if, but event when i remove it, error doesn't goes away, and shows same line, 16
