Sep 20 16:07:22 ip-172-31-1-97 web: at org.binchoo.paimonganyu.chatbot.views.dailycheck.DailyCheckListView.renderBlockButton(DailyCheckListView.java:144) ~[classes!/:na]

• Line 144: Here makes the NullPointerException, which means DailyCheckIn's block id cannot be resolved normally.
• Also, you MUST input a piece of extra information to call the DailyCheckIn block. https://github.com/binchoo/PaimonGanyu/blob/93c93c21a8bf2fd5a7cd48d7252265fee5e8057f/PaimonGanyu/paimonganyu-app/paimonganyu-skill/src/main/java/org/binchoo/paimonganyu/chatbot/views/dailycheck/DailyCheckListView.java#L142-L147

To-be:

1. Fix the constructor signature to get a Blocks singleton from external.
   https://github.com/binchoo/PaimonGanyu/blob/93c93c21a8bf2fd5a7cd48d7252265fee5e8057f/PaimonGanyu/paimonganyu-app/paimonganyu-skill/src/main/java/org/binchoo/paimonganyu/chatbot/views/dailycheck/DailyCheckListView.java#L39-L41

 public DailyCheckListView(Images images, QuickReplies quickReplies, Blocks blocks) { 
     super(images, quickReplies, blocks); 
 } 

2. Set extra information before calling the DailyCheckIn block.

   private List<Button> renderBlockButton(int index) { 
    return List.of(BlockButton.builder() 
            .blockId(blocks().findByFallbackMethod(FallbackMethods.DailyCheckIn))
            .extra(Map.of("index", index)) 
            .label("호요랩 출석 요청") 
            .build()); 
   }
