在Hyperledger Fabric中执行事务时出错

Question

我正在超级账本结构上执行chaincode事务，但是出现了一些奇怪的错误，如下所示：

2019-07-01T07:21:40.006Z - warn: [Transaction]: _validatePeerResponses: Received error response from peer: message=2 UNKNOWN: Transaction is not valid. Got [d9be41c821926332edc7107655fa4e7c31d34cc5cfbcb4bbc54c658b254c6c1e], expected [239121c61652599982cb82e3a25065d04187d73391c17bb26d9584c7e8b6dee8], stack=Error: 2 UNKNOWN: Transaction is not valid.

有时交易得到处理，但有时却给我这个错误

Answer 1

错误是名称未定义在

/home/ubuntu/app/express-api-app-v2.js行号310

由于您要发送的字段未定义，因此链码抛出错误。
