我正在运行byfn教程的修改版，其中包含5个订购者，1个组织，2个同级和1个具有docker-compose的ca服务。我在本地使用node v10.18.1上的macOs Catalina运行节点应用程序。hyperledger fabric version 1.4也正在使用。
[我尝试用connection.json命令提供的容器替换与[c0]到grpcUrl的路径有关的localhost到IP的路径，也没有成功替换到docker inspect的路径，也使用telnet来grep暴露的端口并运行0.0.0.0，以检查所有容器是否都在正确的端口上运行。
在我的代码中，我可以成功注册管理员和其他用户，但是当我尝试连接到网关以调用链码时，它会失败。
我一直在我的API日志中收到错误：
docker ps为什么会出现此错误？

标志，确保为同级启用TLS通信。如果未设置为true，则将连接配置文件中的对等URL从CORE_PEER_TLS_ENABLED=true修改为grpcs://localhost:7051
