我已成功用peer chaincode lifecycle提交了链码。当我尝试调用/查询chaincode时，出现此错误：
Error: endorsement failure during invoke. response: status:500 message:"error in simulation: failed to execute transaction f490a9e7bca41ad10f68306decae2fdd73e09a9d5f81da7c9ee5cdc3811b3f27: invalid invocation: chaincode 'emp_chaincode' has not been initialized for this version, must call as init first"
并且在chaincode容器日志中，它显示：

[请让我知道如何解决。
在错误结束时，您具有必须先作为init调用。
我认为您已将peer chaincode lifecycle approveformyorg命令与标志--init-required一起使用。这意味着新链码的首次调用必须使用--isInit标志，例如peer chaincode invoke -C tradechannel -n trade --isInit ...。在第一次“特殊”调用之后，其他调用和查询就可以了。
