Describe the bug When custom metrics are used in hpa, hpa cannot display detailed information. http_server_requests_per_second is a custom metric.

The apiserver interface can be used to obtain user-defined indicator data.

I end up having to run q kubectl command to view my custom metric HPA values and even my normal CPU utilization when I add a custom HPA. The custom HPA does work at least, its just the display.

watch -n 5 "kubectl describe hpa custom-metrics-demo -n demo-namespace | grep -A5 'Metrics:'"

browser conole error:
