Null Pointer Exception using Command Handler

Hello, I have an NPE when trying to use command handler in vertx

   TelegramOptions telegramOptions = new TelegramOptions()
            .setBotToken(TELEGRAM_TOKEN);
    CommandHandler commandHandler = new CommandHandler()
            .addCommand(new StartCommand());
    bot = TelegramBot.create(vertx, telegramOptions)
            .receiver(new LongPollingReceiver().onUpdate(commandHandler))
            .start();

StartCommand class:

@BotCommand(message = "^/start")
public class StartCommand extends Command {
   @Override
   public void execute(CommandContext commandContext, Handler<Boolean> handler) {
       getBot().sendMessage(new SendMessage().setChatId(commandContext.getUpdate().getMessage().getChatId()).setText("TEST"));
    handler.handle(Boolean.TRUE);
   }
}

And this is the stacktrace 15:10:33,806 WARN vert.x-eventloop-thread-0 CommandHandler:handle:100 - onUpdate: /start, rifkyaziz 15:10:33,807 ERROR vert.x-eventloop-thread-0
