Error instantiating chaincode in Hyperledger Fabric 1.1.0

Question

I am trying to instantiate chaincode in Hyperledger Fabric peer 1.1.0. I have downloaded 1.1.0 version fabric samples and docker containers. The fabcar application got instantiated successfully.

However when I instantiate my chaincode, the peer quits with the following error.

As I can see above, it is not taking go code from $GOPATH which is /home/ubuntu/software/golang.

I have installed the fabric and samples using the command.

as mentioned in

https://hyperledger-fabric.readthedocs.io/en/release-1.4/install.html

passing arguments "1.1.0 1.1.0 0.4.15"

I could see that the chaincode init method gets executed from the application logs.

func (t *SimpleChaincode) Init(stub shim.ChaincodeStubInterface) pb.Response {
        fmt.Println("Init firing.")

    // Initialize the collection of commercial paper keys
    fmt.Println("Initializing user accounts")
    //t.createUser(stub, []string{"importerBank", "importerBank", "Importer Bank"})
    //t.createUser(stub, []string{"customs", "customs", "Customs"})
    //t.createUser(stub, []string{"exporterBank", "exporterBank", "Exporter Bank"})
    //t.createUser(stub, []string{"exporter", "exporter", "Exporter"})

    fmt.Println("Initializing LC keys collection if not present")
    valAsbytes, err := stub.GetState("LCKeys")
    if err == nil {
            var keys []string
            err = json.Unmarshal(valAsbytes, &keys)
            fmt.Println("Existing LC : %v", keys);
            if len(keys) > 0 {
                    for _, key := range keys {
                            valAsbytes, err := stub.GetState(key)
                            if err == nil {
                                    var lc LC
                                    err = json.Unmarshal(valAsbytes, &lc)
                                    if err == nil {
                                            if lc.CurrentStatus == "" {
                                                    lc.CurrentStatus = "Created"
                                                    keysBytesToWrite, _ := json.Marshal(lc)
                                                    if err == nil {
                                                            err = stub.PutState(key, keysBytesToWrite)
                                                            if err != nil {
                                                                    fmt.Println("Error writing LC to chain" + err.Error())
                                                            }
                                                    }
                                            }
                                    }
                            }
                    }
            }
    }

    fmt.Println("Initialization complete")

I would like to know why the peer quits? orderer.example.com: container_name: orderer.example.com image: hyperledger/fabric-orderer environment:

Try adding - GODEBUG=netdns=go in the environment section of the docker compose file for every peer and orderer.
