如何解决通道mychannel的getConfigBlock失败，对等fabric-dev-peer1-org1状态失败，详细信息：找不到频道“ mychannel”
尝试启动结构网关应用程序客户端时，获取以下异常。
org.hyperledger.fabric.sdk.exception.ProposalException：通道mychannel的getConfigBlock失败，同级fabric-dev-peer1-org1。状态失败，详细信息：找不到频道“ mychannel” *
客户端能够正常连接。但是重新启动对等容器后，应用程序客户端无法连接。下面是错误。但是，我可以在/tmp/org1/peer1/configtx这个位置看到peer1中的mychannel.block
我在上面的文件夹中看到了这些文件-channel.tx，mychannel.block，peerUpdate.tx
关于该对等方的证书，我将它们保留在持久性卷上，因此不必认为我需要在重新启动后注册对等方，因为它将使用旧版本。
下面是错误跟踪，执行此代码时失败

有人知道为什么吗？非常感谢对此的任何建议！
解决方法
将结构映像从hyperledger / fabric-peer：2.0升级到hyperledger / fabric-peer：2.2之后，我意识到了。 虽然，我可以在预期位置看到与通道相关的bock mychannel.block。但是，一些未考虑的方式。因此，我重新创建了频道，并将同级加入该频道，然后安装了链码。
此后，我的客户端应用程序就可以连接到对等端而没有任何问题。
不确定这种方法是否正确，但解决了此问题。
