【问题描述】：

我已经部署了基于路径的路由的 ALB 入口控制器，在部署 application-ingress.yaml 文件后，定义的路径在 AWS 控制台中按照我们的预期创建，并且目标组也很健康。

但它只工作 /*，其余路径（/app1，/app2）不工作，出现错误 404。请找到下面的入口 yaml 文件。

Let's say when I'm trying to access /app1 page https://my-domain-name/app1 getting error HTTP ERROR 404

Same way /app2 page https://my-domain-name/app2 getting error HTTP ERROR 404

And last one is /app3 page https://my-domain-name/app3 page is working as we expected

请删除通配符 *，然后检查它是否会开始工作
