我无法在hyperledger faric中运行ibm evote区块链应用程序。我正在ubuntu 16的VS Code（v1.39）中使用IBM Evote。启动本地结构（1 org本地结构）时，我面临以上错误。 以下是我的local_fabric_connection.json文件代码

{
    "name": "local_fabric","version": "1.0.0","client": {
        "organization": "Org1","connection": {
            "timeout": {
                "peer": {
                    "endorser": "300"
                },"orderer": "300"
            }
        }
    },"organizations": {
        "Org1": {
            "mspid": "Org1MSP","peers": [
                "peer0.org1.example.com"
            ],"certificateAuthorities": [
                "ca.org1.example.com"
            ]
        }
    },"peers": {
        "peer0.org1.example.com": {
            "url": "grpc://localhost:17051"
        }
    },"certificateAuthorities": {
        "ca.org1.example.com": {
            "url": "http://localhost:17054","caName": "ca.org1.example.com"
        }
    }
