为链代码构建描述符失败

failed constructing descriptor for chaincodes

我正在尝试与用户进行交易,但是当我尝试获取频道时出现此错误:

微服务日志:

配置:

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

总的来说,如果我从 org1 Peer 执行相同的事务,我会在 peer 上收到类似的错误,两者都失败了。如果我从联盟中删除一个组织,它会在该组织中工作,但当两者都存在时则不会

知道如何解决这个问题吗?

问题可能来自configtx.yaml,你必须正确放置所有的“MSPDir”,当你发出命令时,你必须根据那个“MSPDir”设置环境变量。

所以问题出在为组织创建锚节点的脚本上,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。

通常,如果交易中使用的链代码名称与将链代码部署到网络中时使用的名称不匹配,则会出现此错误。

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并确保链码名称相同(注意 upper/lower 情况) 如果你是运行 FB测试网可以用

./monitordocker.sh fabric_test
