我是新来hyperledger和正在经历的例子在这里。我试图绕过chaincode，但现在停留在我应该升级chaincode的部分
我试图在Docker对等节点内执行对等链代码升级：
peer chaincode upgrade -n tuna-app -p github.com/tuna-app
但最终出现错误
Error getting (testchainid) orderer endpoint: Error endorsing GetConfigBlock: rpc error: code = Unknown desc = chaincode error (status: 500, message: "GetConfigBlock" request failed authorization check for channel [testchainid]: [Failed to get policy manager for channel [testchainid]])
