我正在寻找有关Hyperledger Fabric频道创建的帮助。我是面料初学者。我已经使用Nodejs，Go和HL Composer开发了项目。现在，我正在尝试使用fabric-sdk-java。我使用了标准的fabric-sdk-java余额转移示例。工作正常。
https://github.com/siyuyifang/balance-transfer-java
但是该示例在Fabric版本1.0和fabric-sdk-java v1.0中。因此，我将byfn和docker-composer升级到了当前版本v1.3。一切看起来都很好-生成了byfn，docker yaml，证书和msp。我可以注册用户。但是我在创建频道时遇到问题。后端出现PFB错误。[spring]

我尽了最大的努力。我在crypto-config.yaml中进行了许多更改，现在我相信它是完美的。请让我知道我哪里出了问题。
