Hyperledger fabric未能提交交易：错误：没有可用于{“链码”：[{“名称”：“fabcar”}]}的背书计划

Question

我正在使用hyperledger结构网络，使用结构示例中的基本网络。基本网络由一个订购方和一个对等方组成。我已经在网络上安装了fab汽车连锁码并加入了该频道。请建议我如何将背书政策添加到链码中，下面是我用来启动链码的命令

 1. peer chaincode install -n fabcar -p github.com/ -v 1.1

 2. peer chaincode instantiate -o orderer.example.com:7050 -C mychannel -c '{"Args":[]}'  -n fabcar -v 1.1 -P "OR('Org1MSP.peer','Org1MSP.admin','Org1MSP.member')"

我正在使用fabric sdk查询fabcar，它运行良好。但如果我试图调用链码，它会给我错误声明

未能提交交易：错误：{“链码”：[{“名称”：“fabcar”}]}没有可用的背书计划

调用函数

异步函数调用（userwallet、usename、channelName、chaincodeName）{try{

    // Create a new file system based wallet for managing identities.
    const walletPath = path.join(process.cwd(), 'wallet');
    const wallet = new FileSystemWallet(walletPath);
    console.log(`Wallet path: ${walletPath}`);

    // Check to see if we've already enrolled the user.
    const userExists = await wallet.exists(userwallet);
    if (!userExists) {
        console.log('An identity for the user "user1" does not exist in the wallet');
        console.log('Run the registerUser.js application before retrying');
        return;
    }

    // Create a new gateway for connecting to our peer node.
    const gateway = new Gateway();
    await gateway.connect(ccp, { wallet, identity: usename, discovery: { enabled: true, asLocalhost: true} });

    // Get the network (channel) our contract is deployed to.
    const network = await gateway.getNetwork(channelName);

    // Get the contract from the network.
    const contract = network.getContract(chaincodeName);

    // Submit the specified transaction.
    // createCar transaction - requires 5 argument, ex: ('createCar', 'CAR12', 'Honda', 'Accord', 'Black', 'Tom')
    // changeCarOwner transaction - requires 2 args , ex: ('changeCarOwner', 'CAR10', 'Dave')
    await contract.submitTransaction('createCar','CAR12', 'Honda', 'Accord', 'Black', 'Tom');
    //await contract.submitTransaction('changeCarOwner', 'CAR10', 'Dave');
    console.log('Transaction has been submitted');


    // Disconnect from the gateway.
    await gateway.disconnect();

这很奇怪，让我们做一些尝试和错误

尝试在下面的片段中进行更改。这将删除策略，不要担心默认策略将适用

peer chaincode instantiate -o orderer.example.com:7050 -C mychannel -c '{"Args":[]}'  -n fabcar -v 1.1
