我使用的是hyperledger结构网络，使用的是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汽车链代码并加入了渠道。请建议我如何将背书策略添加到链码中，以下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代码，它会给我错误，说明
未能提交交易：错误：没有可用于｛"链码"：[｛"名称"："fabcar"｝]｝的背书计划

异步函数Invoke(userwallet，usename，channelName，chaincodeName({尝试｛
// Create a new file system based wallet for managing identities.
const walletPath = path.join(process.cwd(), 'wallet');
const wallet = new FileSystemWallet(walletPath);

await gateway.disconnect();

module.exports.Invoke = Invoke
这很奇怪，让我们做一些试错
请尝试在下面的代码段中进行更改。这删除了策略，不用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
