I am using kubernetes version Client Version: v1.22.0 Server Version: v1.24.1

I have installed metrics server by using below command and URL.

kubectl apply -f https://github.com/kubernetes-sigs/metrics-server/releases/download/v0.7.2/components.yaml

I can get the output successfully using "kubectl top nodes:" command. but Unable to get the metrics on "kubectl top pods" command. getting below error.

error: Metrics not available for pod kube-system/cadvisor-6rp4r, age: 2709h18m37.384021169s

I tried with other namespace also but same error "error: Metrics not available for pod xxx"
