当尝试实例化链式代码时，错误

Question

我正在研究Fabric ca操作指南文档。但是，当我尝试实例化chaincode时，发生了错误。实例化命令：

peer chaincode instantiate -C mychannel -n mycc -v 1.0 -c '{"Args":["init","a","100","b","200"]}' -o orderer1-org0:7050 --tls --cafile /tmp/hyperledger/org2/peer1/tls-msp/tlscacerts/tls-0-0-0-0-7052.pem

错误消息：

Error: could not assemble transaction, err proposal response was not successful, error code 500, msg transaction returned with failure: Attribute 'abac.init' was not found

有人可以向我解释吗？谢谢

实例化时正在调用您的Init函数，但失败。

我想您的链码是https://github.com/hyperledger/fabric-samples/blob/release-1.4/chaincode/abac/go/abac.go。事实是，请求者证书应将属性“ abac.init”设置为true，而您的证书则没有。这是在Fabric CA注册期间定义的，并包含在您的注册证书中。
