问题描述

我正在尝试从用户那里进行交易,但是当我尝试获取频道时,我收到了这个错误:

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:

配置:

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

总体而言,如果我从 org1 Peer 执行相同的事务,我会在对等端收到类似的错误,两者都失败了。如果我从联盟中删除一个组织,它正在从该组织工作,但当两者都存在时不会

知道如何解决这个问题吗?

解决方案


通常,如果交易中使用的链码名称与将链码部署到网络中时使用的名称不匹配,则会发生此错误。

有时,如果链码未实例化或未在通道中定义,则会发生这种情况。最好检查 Docker 容器以了解此错误背后的原因并确保链代码名称相同(注意大写/小写)如果您正在运行 FB 测试网络,您可以使用

./monitordocker.sh fabric_test
