无法将业务网络模型部署到作曲家游乐场吗？

Question

我对Hyperledger Fabric作品很陌生。我已经建立了一个业务网络，然后创建了.bna文件，并尝试将其部署到composer-playground。然后它向我显示了这样的错误。

Cannot import an invalid Business Network Definition. Found SyntaxError: Unexpected token (27:6)

这是我的商业网络模式文件。

namespace org.landreg

abstract concept Address {
  o String addressLine
  o String locality
}

concept DutchAddress {
  o String postalCode regex=/\d{4}[ ]??[A-Z]{2}/
}

enum Gender {
  o FEMALE
  o MALE
}

participant Individual identified by passportNumber{
  o String passportNumber
  o DutchAddress address
  o Gender gender
}

asset  LandTitle identified by id {
  o String id
  o DutchAddress address
  o Integer area range=[1000,]
  o Boolean forSale default=false
  o Double price optional
  --> Individual owner
  --> Individual[] previousOwners
}

abstract transaction UnlockLandTitle {
  -->LandTitle landTitle
}

这是我的logic.js文件。

const NS = "org.landreg";

/**
 * Sample transaction
 * @param {org.landreg.UnlockLandTitle} //transaction object define in the cto file
 * @transaction

async function unlockLandTitle(tx) {
  //Get asset registery for landTitles
  const landTitleRegistry = await getAssetRegistry(NS + ".LandTitle");

  if (tx.landTitle.forSale) {
    throw new Error(
      `Land Title with id ${tx.landTitle.getIdentifier()} is already unlocked for sale`
    );
  }

  // Unlock asset to be for sale 
  tx.landTitle.forSale = true;

  await landTitleRegistry.update(tx.landTitle);
}

我进行了搜索，但是找不到适合我问题的答案。有人可以帮我解决这个问题吗？谢谢。

注意： 当我得到建议通过在@Param行中添加事务实例来更改代码后，这就是在操场上向我展示的方式。有人可以给我更多解决方案来解决此问题吗？非常感谢你！！ 问题：

Answer 1

您忘记在unlockLandTitle文件中写入 logic.js 。

只需替换此行：

* @param {org.landreg.UnlockLandTitle} //transaction object define in the cto file

使用

 * @param {org.landreg.UnlockLandTitle} unlockLandTitle //transaction object define in the cto file
