Question

我正在尝试与用户进行交易，但是当我尝试获取频道时，会出现此错误：

微服务日志：

error: [DiscoveryService]: send[mychannel] - Channel:mychannel received discovery error:failed constructing descriptor for chaincodes:<name:"mychannel" >

对等日志：

Configtx：

    mychannel:
        Consortium: MyConsortium
        <<: *ChannelDefaults
        Application:
            <<: *ApplicationDefaults
            Organizations:
                - *Org1
                - *Org2
            Capabilities:
                <<: *ApplicationCapabilities

总的来说，如果我正在从org1对等方执行相同的事务，那么对等方都将收到类似的错误，都将失败。如果我从联合体中删除一个组织，则该组织正在该组织中工作，但是当这两个组织都存在时，则无法工作

有什么办法解决这个问题吗？

Answer 1

如果 Chaincode 未实例化或未在通道中定义，有时会发生这种情况。最好检查 Docker 容器以了解此错误背后的原因。如果您正在运行 FB 测试网络，您可以使用

./monitordocker.sh fabric_test

Answer 2

问题可能出在configtx.yaml，您必须正确放置所有“ MSPDir”，并且在发出命令时，必须根据该“ MSPDir”设置环境变量。

Answer 3

所以问题出在脚本上，该脚本为组织创建锚点对等，错误通过bash泄漏。在为两个组织添加锚点后，事情就解决了，我可以进行交易了。

链码构造描述符失败
