Hyperledger Composer с пользовательскими ошибками в IBM Cloudant Wallet - слишком большая сущность

0 голосов
/ 11 ноября 2018

Я создаю сервер nodejs, куда добавляю участников и создаю карты в облачном кошельке. Из того, что я узнал из игры с композитором sdk, я закончил тем, что создал функцию, которая берет данные об участнике, затем выдает удостоверение личности, а затем создает карту в облачном хранилище. Этот метод работал нормально до сегодняшнего дня.

Внезапно я получаю 413. - Слишком большой объект, когда я пытаюсь импортировать карту.

Есть предложения? 

const BusinessNetworkConnection = require("composer-client")
  .BusinessNetworkConnection;
const NetworkCardStoreManager = require("composer-common")
  .NetworkCardStoreManager;

const IdCard = require("composer-common").IdCard;

const connectionProfile = JSON.parse(
  JSON.stringify(require("./connection-profile.json"))
);

const walletType = {
  type: "@ampretia/composer-wallet-cloudant",
  options: {
    database: "composer-wallets",
    apikey: "",
    host: "",
    iam_apikey_description: "",
    iam_apikey_name: "",
    iam_serviceid_crn: "",
    password: "",
    port: ,
    url: "",
    username: ""
  }
};

const AdminConnection = require("composer-admin").AdminConnection;

const cardStore = NetworkCardStoreManager.getCardStore(walletType);

const bnConnection = new BusinessNetworkConnection({ cardStore });

const adminConnection = new AdminConnection({ cardStore });


const addParticipantAndIssueIdentity = userDetails => {
  return new Promise(async (resolve, reject) => {
    try {
      await adminConnection.connect("admin@test.com");

      const definition = await bnConnection.connect(
        "admin@test.com"
      );

      const participantRegistry = await bnConnection.getParticipantRegistry(
        `org.test.bna.${userDetails.role}`
      );
      const factory = definition.getFactory();
      let participant = factory.newResource(
        "org.test.bna",
        `${userDetails.role}`,
        `${userDetails.uid}`
      );
      participant.email = userDetails.email;
      participant.firstName = userDetails.firstName;
      participant.lastName = userDetails.lastName;
      await participantRegistry.add(participant);
      const returnedCard = await bnConnection.issueIdentity(
        `org.test.bna.${userDetails.role}#${userDetails.uid}`,
        `${userDetails.uid}`
      );

      const metadata = {
        userName: returnedCard.userID,
        version: 1,
        enrollmentSecret: returnedCard.userSecret,
        businessNetwork: "test"
      };

      const idCard = new IdCard(metadata, connectionProfile);

      console.log("Importing Card 1");
      await adminConnection.importCard(
        `${userDetails.uid}@test`,
        idCard
      ); <----- This call is failing
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
      console.log("Request Identity");
      const result = await adminConnection.requestIdentity(
        `${userDetails.uid}@test`,
        returnedCard.userID,
        returnedCard.enrollmentSecret
      );

      idCard.setCredentials({
        ...result,
        privateKey: result.key
      });

      console.log("Importing Card 2");
      await adminConnection.importCard(
        `${userDetails.uid}@test`,
        idCard
      );

      console.log("Exporting Card");
      await adminConnection.exportCard(
        `${userDetails.uid}@test`
      );
      resolve(true);
    } catch (error) {
      console.log(error);
      reject(error);
    }
  });
};

UPDATE:

Я добавил журнал ошибок ниже:

Все версии Cloudant в IBM Cloud предполагают максимальный размер документа 1 мегабайт. Обойти это невозможно и относится как к бесплатной, так и к платной версиям. Смотри https://console.bluemix.net/docs/services/Cloudant/api/document.html#documents

Эффективная архитектура данных для Cloudant обычно использует документы размером в несколько килобайт.
