Hyperledger fabric Hyperledger结构：死机：运行时错误：结构/peer/common.NewPeerClientForAddress处的内存地址无效或无指针取消引用

我们正在尝试使用以下命令调用chaincode：

FABRIC_CFG_PATH=${PWD} CORE_PEER_LOCALMSPID=org1MSP CORE_LOGGING_LEVEL=debug CORE_PEER_TLS_ENABLED=true CORE_PEER_TLS_CLIENTAUTHREQUIRED=true CORE_PEER_MSPCONFIGPATH=msp CORE_PEER_TLS_CLIENTCERT_FILE=user-org1-tls.pem CORE_PEER_TLS_CLIENTKEY_FILE=user-org1-tls.key peer chaincode invoke -C dscsa -n mycc -c '{"Args":["create","00000"]}' -o orderer1-ord:7050 --tls --cafile ord-ca-chain.pem --peerAddresses peer3-org1:7051 --tlsRootCertFiles org1-ca-chain.pem --peerAddresses peer3-org2:7051 --tlsRootCertFiles org2-ca-chain.pem --peerAddresses peer3-org3:7051 --tlsRootCertFiles org3-ca-chain.pem

但是得到这个错误：

我们正在使用v1.3版的fabric。如何解决此问题？

如果

核心对等客户端证书文件

或

核心对等客户端密钥文件

不存在，则可能发生上述错误。您不会得到一个错误，说文件不存在。相反，您会得到上面的错误

此外，还需要设置和

CORE\u PEER\u TLS\u ROOTCERT\u文件

。如果未设置环境变量，Fabric将使用中的设置来设置这些变量

func NewPeerClientForAddress(address, tlsRootCertFile string) (*PeerClient, error) {
    if address == "" {
        return nil, errors.New("peer address must be set")
    }

    _, override, clientConfig, err := configFromEnv("peer")
    if clientConfig.SecOpts.UseTLS {
        if tlsRootCertFile == "" {
            return nil, errors.New("tls root cert file must be set")
        }
        caPEM, res := ioutil.ReadFile(tlsRootCertFile)
        if res != nil {
            err = errors.WithMessage(res, fmt.Sprintf("unable to load TLS root cert file from %s", tlsRootCertFile))
            return nil, err
        }
        clientConfig.SecOpts.ServerRootCAs = [][]byte{caPEM}
    }
    return newPeerClientForClientConfig(address, override, clientConfig)
}
