Node.js Hyperledger结构1.2功能错误

我正在尝试使用hyperledger结构示例网络和我自己的链码。 我正在使用，但我的链码需要集合配置文件，因为它使用的是私有数据。我添加了SendInstanceProposal请求，但在实例化链码时，我不断收到错误

{"success":false,"message":"Failed to instantiate the chaincode. cause:instantiate proposal resulted in an error :: Error: as V1_2 or later capability is not enabled, private channel collections and data are not available"}

我在artifacts/channel/configtx.yaml文件中添加了capabilities部分，但错误仍在继续。您可以从中查看该文件

那么，如何解决此错误并使此网络与专用通道一起工作？

当应用程序和通道未启用V1.2或更高版本的功能时，会发生此错误

解决方案：

在configtx.yaml文件中添加功能

Capabilities:
    # Channel capabilities apply to both the orderers and the peers and must be
    # supported by both.
    # Set the value of the capability to true to require it.
    Channel: &ChannelCapabilities
        # V1.3 for Channel is a catchall flag for behavior which has been
        # determined to be desired for all orderers and peers running at the v1.3.x
        # level, but which would be incompatible with orderers and peers from
        # prior releases.
        # Prior to enabling V1.3 channel capabilities, ensure that all
        # orderers and peers on a channel are at v1.3.0 or later.
        V1_3: true

    # Orderer capabilities apply only to the orderers, and may be safely
    # used with prior release peers.
    # Set the value of the capability to true to require it.
    Orderer: &OrdererCapabilities
        # V1.1 for Orderer is a catchall flag for behavior which has been
        # determined to be desired for all orderers running at the v1.1.x
        # level, but which would be incompatible with orderers from prior releases.
        # Prior to enabling V1.1 orderer capabilities, ensure that all
        # orderers on a channel are at v1.1.0 or later.
        V1_1: true

    # Application capabilities apply only to the peer network, and may be safely
    # used with prior release orderers.
    # Set the value of the capability to true to require it.
    Application: &ApplicationCapabilities
        # V1.3 for Application enables the new non-backwards compatible
        # features and fixes of fabric v1.3.
        V1_3: true
        V1_2: false
        V1_1: false

然后在配置文件部分应用它们

可能您正在运行较旧版本的hyperledger fabric。我认为版本是正确的，因为我通过编辑runApp.sh设置了版本，并添加了
export IMAGE\u TAG=“1.2”
