I was trying to configure the external metrics with the hpa by using latency but i'm, getting the following error:

Warning FailedGetExternalMetric horizontal-pod-autoscaler unable to get external metric bt-mservices/loadbalancing.googleapis.com|https|backend_latencies/&LabelSelector{MatchLabels:map[string]string{resource.labels.backend_name: k8s1-daea7033-bt-mservices-core-api-service-80-eb0aa30d,},MatchExpressions:[]LabelSelectorRequirement{},}: unable to fetch metrics from external metrics API: Distributions are not supported
