我安装了kube prometheus stack helm chart。图表显示安装在我的3节点Kubernetes集群（1.27.3）上没有问题。所有部署和吊舱似乎都进入了就绪状态。端口转发了prometheus pod并尝试连接，但无法连接。
当我查看prometheus pod的日志时，似乎有一个错误或警告，说明它生成的规则集有问题：

我是普罗米修斯的新手，所以我不确定该找什么或如何解决这个问题。有人可以帮助我理解：
1.此错误是什么原因引起的？
1.如何修复此错误？
它似乎是cube-system命名空间中的某个东西，但我在该命名空间中只有3个pod，它们都具有唯一的名称：
CoreDNS Local Path Provisioner metrics-server
我感谢任何帮助或建议，如何解决这个问题。
