我正在通过Spring Cloud，Spring
Boot和Docker构建应用程序。整个应用程序运行正常。我有几个微服务。每个项目都在Docker上运行。当我尝试通过Zuul
API网关使用微服务时，第一次调用时出现错误。但是，如果我刷新浏览器，它就可以正常工作。错误如下-

我已经为所有项目创建了图像。并将其推送到DockerHub中。Docker-Compose文件也将其推送到GitHub中。下面是路径。

https://github.com/numery009/DockerCompose/blob/master/docker-
compose.yaml

我还将其部署在EC2的Docker Swarm上。但是，当我尝试通过Zuul使用微服务时，它根本无法工作。对于每个请求，我都会收到相同的“过滤器错误”。

请帮忙！！！。
