升级hyperledger fabric网络后，通道创建失败

Question

我将开发超级分类账结构网络从1.4.1更新到1.4.4，不能再创建通道或与网络交互，因为在v1.4.1中没有失败的通道策略失败了

下面是当我试图通过节点sdk创建一个通道时所发生的事情

节点sdk中的错误

error: Status: BAD_REQUEST
Info: error validating channel creation transaction for new channel 'mychannel', could not successfully apply update to template configuration: error authorizing update: error validating DeltaSet: policy for [Group]  /Channel/Application not satisfied: implicit policy evaluation failed - 0 sub-policies were satisfied, but this policy requires 1 of the 'Admins' sub-policies to be satisfied

订单码头集装箱中的错误

[orderer.common.broadcast] ProcessMessage -> WARN 00e [channel: farm] Rejecting broadcast of config message from 172.18.0.1:40866 because of error: error validating channel creation transaction for new channel 'farm', could not succesfully apply update to template configuration: error authorizing update: error validating DeltaSet: policy for [Group]  /Channel/Application not satisfied: implicit policy evaluation failed - 0 sub-policies were satisfied, but this policy requires 1 of the 'Admins' sub-policies to be satisfied

密码配置部分

Application: &ApplicationDefaults

    # Organizations is the list of orgs which are defined as participants on
    # the application side of the network
    Organizations:

    # Policies defines the set of policies at this level of the config tree
    # For Application policies, their canonical path is
    #   /Channel/Application/<PolicyName>
    Policies:
        Readers:
            Type: ImplicitMeta
            Rule: "ANY Readers"
        Writers:
            Type: ImplicitMeta
            Rule: "ANY Writers"
        Admins:
            Type: ImplicitMeta
            Rule: "MAJORITY Admins"

Answer 1

在使用用于v1.4.4的fabric样例configtx.yaml作为模板之后，我发现唯一的区别是这个Capabilities部分

Application: &ApplicationDefaults

    # Organizations is the list of orgs which are defined as participants on
    # the application side of the network
    Organizations:

    # Policies defines the set of policies at this level of the config tree
    # For Application policies, their canonical path is
    #   /Channel/Application/<PolicyName>
    Policies:
        Readers:
            Type: ImplicitMeta
            Rule: "ANY Readers"
        Writers:
            Type: ImplicitMeta
            Rule: "ANY Writers"
        Admins:
            Type: ImplicitMeta
            Rule: "MAJORITY Admins"

    Capabilities:
        <<: *ApplicationCapabilities

Answer 2

我认为在1.4.3中出现了一些频道策略和信道能力的变化

我解决了这个问题，方法是从第一个网络获得1.4.3 fabric示例的configtx.yaml，并将我的更改(org名称等)应用到这个新的yaml文件中。然后产生一个新的成因块等。
