Hyperledger Fabric自定义链式代码调用失败

Question

我试图运行自定义链式代码。我是能够成功地部署，但是当我使用运行调用命令：

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

面对这样的错误消息：对等chaincode的成功部署后

Error: Error endorsing chaincode: rpc error: code = 2 desc = Error deploying chaincode: Failed to launch chaincode spec(Could not get deployment transaction from LCCC for mycc - Error deploying chaincode: Transaction or query returned with failure: transaction not found default/mycc)

日志（运行在DEV模式等） ：

任何指向我出错的地方都会很棒。提前致谢。

对invoke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，可以尝试链码ID而不是链码名称。

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”标题下。
