Hyperledger-Fabric Node SDK-曲线属性错误

Question

将节点项目部署到Heroku时遇到问题。

由于来自fabri-client包的依赖性，出现了一个恒定错误。

错误为： "Cannot read property 'curve' of undefined" 。 我还不清楚为什么。

所有生成的文件都已经过验证（证书文件，pem和所有配置文件）。 它在生产和本地上完全相等。

似乎是有关某些文件或属性无法读取的错误。 我已经看了很多，却一无所获。

谢谢！

Answer 1

我遇到了同样的问题，对我有用的是

1. 确保在package.json中使用最新版本的“ fabric-ca-client”和“ fabric-client”作为节点模块（基本上，它应与您尝试连接的Fabric版本匹配）。
2. 使用示例应用程序（fabcar）随附的最新版本的invoke.js / query.js（新版本中存在一些细微差异）。

注意：就我而言，出现此问题是因为我使用的是客户端代码的1.3版本，而我的超级账本结构为1.4版本

Answer 2

这是由于fabric-client-kv- *文件夹中的证书无效/过期。

解：

1. 删除或备份fabric-client-kv- *文件夹的内容。
2. 再次注册管理员用户。
3. 立即注册普通用户。

如果找不到证书文件夹，请在程序中查找以下行，

var store_path = path.join(__dirname, 'hfc-key-store');

要么

  credentialStore:
    # [Optional]. Specific to FileKeyValueStore.js or similar implementations in other SDKs. Can be others
    # if using an alternative impl. For instance, CouchDBKeyValueStore.js would require an object
    # here for properties like url, db name, etc.
    path: "./fabric-client-kv-org1"

“ hfc-key-store”或“ fabric-client-kv-org1”是包含证书的文件夹。
