Question

我正在使用Hyperledger Fabric Go SDK调用链式代码事务，但是出现错误提示：

ENDORSEMENT_POLICY_FAILURE. Description: received invalid transaction

在将链码实例化为两个 Org 时，我已经设置了背书策略。

configtx.yaml

链码声明

ccPolicy := cauthdsl.SignedByAnyPeer([]string{"AND ('Org1MSP.peer', 'Org2MSP.peer')"})

resp, err := resMgmt.InstantiateCC(
    setup.Org.ChannelID,
    resmgmt.InstantiateCCRequest{
        Name:    chaincodeId,
        Path:    setup.Org.ChaincodeGoPath,
        Version: setup.Org.OrgChaincodeVersion,
        Args:    [][]byte{[]byte("init")},
        Policy:  ccPolicy,
    },resmgmt.WithRetry(retry.DefaultChannelOpts),resmgmt.WithTargets(setup.Org.OrgPeers[0]))

链式代码调用

response, err := channelClient.Execute(channel.Request{

        ChaincodeID: chaincodeId, 
        Fcn: fcnName, 
        Args: args, 
        TransientMap: transientDataMap,
},channel.WithRetry(retry.DefaultChannelOpts),channel.WithTargetEndpoints("grpcs://localhost:7051", "grpcs://localhost:9051"))

Chaincode实例化成功，并且我可以在两个对等Docker容器中看到链码，但是在将数据调用到链码中时，我遇到了 ENDORSEMENT_POLICY_FAILURE 错误。

我还需要制定其他政策吗？请给我建议一些解决方案，我做错了什么？。

ENDORSEMENT_POLICY_FAILURE。说明：收到无效交易
