Hyperledger fabric 链码错误（状态：500，消息：智能合约功能名称无效

我正在尝试在Hyperledger结构上创建一个应用程序。我已经在GO中编写了智能合约，并尝试使用nodejs脚本调用它。但下面是一个错误

我将遵循本教程：

来自对等方的错误日志：

2018-05-16 15:52:31.399 UTC [endorser] ProcessProposal -> ERRO 03f [kyc-channel][bbad7222] simulateProposal() resulted in chaincode name:"kyc"  response status 500 for txid: bbad72223a50793f012bd76bd902a816807bde759e639dc6805db70aec41df4e

来自invoke.js的请求

var request = {
    //targets: let default to the peer assigned to the client
    chaincodeId: 'kyc',
    fcn: 'updateUser',
    args: ['USER1','bengaluru'],
    chainId: 'kyc-channel',
    txId: tx_id
};

智能合约的调用功能：

    if function == "queryUser" {
        return s.queryUser(APIstub, args)
    } else if function == "initLedger" {
        return s.initLedger(APIstub)
    }else if function == "updateUser" {
        return s.updateUser(APIstub, args)
    }
    return shim.Error("Please provide valid SmartContract name")
}

有人能帮忙解释为什么它显示了无效的智能合约函数名吗。？ 我能够成功地调用queryUser和initLedger函数

当我试图直接从cli容器执行链码时出现以下错误

问题解决了

fabric使用的是旧链码docker图像。 我必须删除以前生成的链码docker映像，它没有updateUser函数

另一种方法是更新chaincode的版本或更改其名称
