Solved Just showing usage

I stopped doing plugins for 6 monts and now i have a problem and i dont see where is my error, this code is just returning the usage:

PHP:

public class tpgive implements CommandExecutor {
    Main plugin;
     public tpgive(Main instance) {
    plugin = instance;
    }

    @Override
    public boolean onCommand(CommandSender sender, Command cmd, String label, String[] args) {
        if(cmd.getName().equalsIgnoreCase("tpbook")) {
            if(sender instanceof Player) {
                Player player = (Player) sender;
                if(player.hasPermission("etb.give")) {
                    player.getInventory().addItem(plugin.tpBook());
                    return true;
                } else {
                    player.sendMessage(ChatColor.RED + "You don't haver permission to do this!");
                    return true;
                }
              
            }
        }
      
      
        return true;
    }

}
