Hyperledger Fabric自定义链代码调用失败

我正在尝试运行自定义链代码 . 我能够成功部署它，但是当我使用以下命令运行invoke命令时：

peer chaincode invoke -n mycc -c '{"Args":["write","hello_world", "200"]}'

面对此错误消息：

错误：错误支持链代码：rpc错误：代码= 2 desc =部署链代码时出错：无法启动链代码规范（无法从LCCC获取mycc的部署事务 - 错误部署链代码：返回失败的事务或查询：未找到事务默认值/ mycc）

在对等体上成功部署链码后记录（在DEV模式下运行对等体）：

任何关于我出错的指针都会很棒 . 提前致谢 .

    对调用语法的一些修改可能会有所帮助 .

    • 如果启用了安全性，则应使用-u参数指定已注册的用户 .

    • 对于-n参数，可以尝试使用链代码ID而不是链代码名称 .

    调用的示例语法包含在https://hub.docker.com/r/ibmblockchain/fabric-peer/的“测试和验证本地网络” Headers 下 .

    您是否确保在运行此命令之前设置了环境变量，一旦您重新进入对等容器，您需要这样做 . 此外，在调用chaincode时，您需要传递一些标志及其选项 .

    尝试这样的命令：

    ***peer chaincode invoke -o <orderer-string>:<port> --tls --cafile <permissions-path-which-is-.pem-file> -C $CHANNEL_NAME -n mycc -c '{"Args":["write","hello_world", "200"]}'***
