could not create channel group: error adding policies to channel group: no policies defined的解决方案

执行config_raft文件夹中./generate.sh脚本报错：

Error on outputBlock: could not create bootstrapper: could not create channel group: error adding policies to channel group: no policies defined

意思是没有定义通道组的策略

从上图中看出没有生成通道交易文件mychannel.tx和创世区块genesis.block

我的解决方案是改写configtx.yaml文件，如下所示

改写完成后删除crypto-config文件夹，并重新执行生成指令：

./generate.sh

如图所示，报错内容消失并成功生成生成通道交易文件mychannel.tx和创世区块genesis.block。
