Firebase-Admin SetValueAync（）未更新数据库

Question

我正在使用SetValueAsync（）并传递HashMap来更新数据库，代码在一台笔记本电脑上运行正常，但是当我尝试在另一台笔记本电脑上运行相同的代码时。尽管它没有给出任何错误，但是没有更新数据库。
这是初始化应用的代码

FileInputStream serviceAccount =
                              new FileInputStream("src/Files/serviceAccountKey.json");
                            FirebaseOptions options = new FirebaseOptions.Builder()
                              .setCredentials(GoogleCredentials.fromStream(serviceAccount))
                              .setDatabaseUrl("https://news-article-summarizer.firebaseio.com")
                              .build();

                            FirebaseApp.initializeApp(options);
                        //final FirebaseDatabase database = FirebaseDatabase.getInstance();
                            DatabaseReference ref = FirebaseDatabase.getInstance().getReference("database");
                                ref.addListenerForSingleValueEvent(new ValueEventListener() {
                                  @Override
                                  public void onDataChange(DataSnapshot dataSnapshot) {
                                    Object document = dataSnapshot.getValue();
                                    System.out.println(document);
                                  }

                                  @Override
                                  public void onCancelled(DatabaseError error) {
                                  }
                                });

这是我要更新数据库的功能

 private static void SaveData(int newsSite,Map<String, Article> dataMap,DatabaseReference ref) {

            switch(newsSite)
            {
                case 1:
                    ref.child("PakObserver").setValueAsync(dataMap);
                    break;
                case 2:
                    ref.child("DawnNews").setValueAsync(dataMap);
                    break;
                case 3:
                    ref.child("TheNation").setValueAsync(dataMap);
                    break;
                case 4:
                    ref.child("TribuneNews").setValueAsync(dataMap);
                    break;
                case 5:
                    ref.child("DailyTime").setValueAsync(dataMap);
                    break;
            }
