Getting unable to read all metrics alert in Google Cloud

Cluster information:

Kubernetes version: 1.21
Cloud being used: Google Cloud

I am newbie in Kubernetes. I am trying to setup dummy Kubernetes cluster from Google Cloud. I don’t have much idea about YAML, so I used UI to create a kubernetes cluster there. Pods are running & cluster is green. But I am seeing unable to read all metrics in Autoscaler. I used UI to create the dummy cluster & entered all the info which was asked By Google. Not sure where it went wrong. Anyone seen the same issue?

Found the issue. My lack of knowledge in YAML settings is the problem. Resources field was not generated from GKE ui. Step by step instruction to fix it is given here How to Resolve Kubernetes Autoscaler Error “Unable to read all metrics” – W3 Spot.
My issue is fixed.
