Unimplemented desc = unbekannt Service protos.ChaincodeSupport

Question

Wenn ich Besteller, Peer-Knoten zu starten, dann beginne ich mit der example01.go die chaincode zu instanziiert, und angeben:

peer.address 192.168.120.189:7051 
chaincode.id.name simple-token:1.0.0 

der Hauptcode von example01.go ist :

func main() { 
    viper.Set("chaincode.id.name","simple-token:1.0.0") 
    err := shim.Start(new(SimpleChaincode)) 
    if err != nil { 
     fmt.Printf("Error starting Simple chaincode: %s", err) 
    } 
} 

in Methode shim.Start() der Fehler tritt in folgenden Satz:

err = chatWithPeer(chaincodename, stream, cc)//causes the error 

aber es Fehler zeigen: Unimplemented desc = unbekannt Service protos.ChaincodeSupport Prozess mit Exit-Code beendet 0

Answer 1

Sie den falschen Port. In v1.1 ist der Port 7052 und nicht 7051 wie es in v1.0 war
