我有一个基本的第一个网络，并与两个组织一起运行，并且两个组织都有两个同级。事务未落实。当我调用时，链码在容器中按预期运行，并按预期返回建议。但是那些没有反映在stateDB中。出现以下错误。
[fabsdk/fab] 2019/08/15 07:54:14 UTC - connection.(*EventHubConnection).Receive -> ERRO Received error from stream: [rpc error: code = Unimplemented desc = unknown service protos.Events]. Sending disconnected event.

代码如下：
reg, notifier, err := event.RegisterChaincodeEvent(fSetup.ChainCodeID, "saveAsset")
if err != nil {
log.Println("Error while registering for the chaincode event")
}
defer event.Unregister(reg)
args = append(args, []byte("{payload}"))
result, errorObj := ch.Execute(channel.Request{
ChaincodeID: fSetup.ChainCodeID,
Fcn: "create",
Args: args,
}, channel.WithRetry(retry.DefaultChannelOpts))
if errorObj != nil {
log.Printf("error for the args %v", errorObj)
}
select {
case ccEventNotify := <-notifier:
fmt.Printf("Received CC event: %v\n", ccEventNotify)
case <-time.After(time.Second * 60):
log.Println("Timeout during chaincode status awaiting")
}
配置几乎如下所示：
