FirebaseMessagingException：调用FCM后端服务时出错

Question

我正在尝试发送fem通知：

MulticastMessage message = MulticastMessage.builder()
            .putData("score", "850")
            .putData("time", "2:45")
            .addAllTokens(requestDTO.getTokenIds())
            .build();


        try {
            firebaseInstance.sendMulticast(message);
        } catch (FirebaseMessagingException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }

现在此代码正在一台服务器上运行，但是当我在不同服务器上运行同一jar时，它会显示异常消息：

我做错了。编译时所有的配置都带有代码。

同一jar能够从一台服务器传递通知，但无法从另一台服务器（2-3台不同服务器）传递通知。

这些服务器被阻止还是什么？我应该如何调试那些？

Firebase配置：

{
  "type": "service_account",
  "project_id": "my-pro",
  "private_key_id": "bbbbbbbbbBbbbbbbbbbbbbbbbbbbbbbbbbbb",
  "private_key": "-----BEGIN PRIVATE KEY-----\nPRIVATE JET CINTEBT\n-----END PRIVATE KEY-----\n",
  "client_email": "firebase-adminsdk-cg2zu@sabncd.iam.gserviceaccount.com",
  "client_id": "12121212121212121212121",
  "auth_uri": "https://accounts.google.com/o/oauth2/auth",
  "token_uri": "https://oauth2.googleapis.com/token",
  "auth_provider_x509_cert_url": "https://www.googleapis.com/oauth2/v1/certs",
  "client_x509_cert_url": "https://www.googleapis.com/robot/v1/metadata/x509/firebase-adminsdk-cg2zu%sabncd.iam.gserviceaccount.com"
}

Firebase实例创建器

@Configuration
public class FirebaseInstanceCreator {

    @Bean
    public FirebaseMessaging firebaseMessaging() throws IOException {
        ClassPathResource classPathResource = new ClassPathResource("serviceAccount.json");
        FirebaseOptions options = new FirebaseOptions   .Builder()
                                                      .setCredentials(GoogleCredentials.fromStream(classPathResource.getInputStream()))
                                                      .build();
        FirebaseApp.initializeApp(options);
        return FirebaseMessaging.getInstance();
    }
}
