What happened?

one or more objects failed to apply, reason: "" is invalid: patch: Invalid value: "map[metadata:map[annotations:map[kubectl.kubernetes.io/last-applied-configuration:{"apiVersion":"autoscaling/v2","kind":"HorizontalPodAutoscaler","metadata":{"annotations":{},"labels":{"argocd.argoproj.io/instance":"agent-productivity-service-dev"},"name":"agent-productivity-service","namespace":"platform"},"spec":{"maxReplicas":"${{ .Values.hpa.tier3.maxReplicas }}","metrics":[{"resource":{"name":"cpu","target":{"averageUtilization":"${{ .Values.hpa.cpu }}","type":"Utilization"}},"type":"Resource"},{"resource":{"name":"memory","target":{"averageUtilization":"${{ .Values.hpa.memory }}","type":"Utilization"}},"type":"Resource"}],"minReplicas":"${{ .Values.hpa.tier3.minReplicas }}","scaleTargetRef":{"apiVersion":"apps/v1","kind":"Deployment","name":"agent-productivity-service"}}}\n]] spec:map[maxReplicas:${{ .Values.hpa.tier3.maxReplicas }} metrics:[map[resource:map[name:cpu target:map[averageUtilization:${{ .Values.hpa.cpu }} type:Utilization]] type:Resource] map[resource:map[name:memory target:map[averageUtilization:${{ .Values.hpa.memory }} type:Utilization]] type:Resource]] minReplicas:${{ .Values.hpa.tier3.minReplicas }}]]": unrecognized type: int32

What did you expect to happen?

I am trying HPA for one service, since hpa values are parsed from group vars, I am getting this error. I tired adding quotes, then it will show helm template error like "Error: failed to parse .agent-productivity-service/values.yaml: error converting YAML to JSON: yaml: invalid map key: map[interface {}]interface {}{".Values.hpa.enabled":interface {}(nil)}"

How can we reproduce it (as minimally and precisely as possible)?

Deployment file is
application: name: agent-productivity-service type: java port: 10490 replicaCount: 1 namespace: platform args: ["{{ .Values.heap.xms }}", "{{ .Values.heap.xmx }}", "{{ .Values.heap.xss }}"] nodeSelector: karpenter.sh/provisioner-name: amd-m6 healthcheck: path: /actuator/health interval: initialDelaySeconds: 50 autoscaling: enabled: ${{ .Values.hpa.enabled }} minReplicas: ${{ .Values.hpa.tier3.minReplicas }} maxReplicas: ${{ .Values.hpa.tier3.maxReplicas }} metrics: cpu: ${{ .Values.hpa.cpu }} memory: ${{ .Values.hpa.memory }} ingress: enabled: true hosts: - host: "aps.{{ .Values.common.internal_domain }}" paths: - path: / pathType: Prefix resources: requests: cpu: "{{ .Values.resources.tier3.requests.cpu }}" memory: "{{ .Values.resources.tier3.requests.memory }}" limits: cpu: "{{ .Values.resources.tier3.limits.cpu }}" memory: "{{ .Values.resources.tier3.limits.memory }}" properties: enabled: true

group vars file
hpa: enabled: true tier1: minReplicas: 1 maxReplicas: 2 tier2: minReplicas: 1 maxReplicas: 2 tier3: minReplicas: 1 maxReplicas: 2 tier4: minReplicas: 1 maxReplicas: 2 cpu: 50 memory: 250

helm template hpa.yaml file is
{{ if .Values.application.autoscaling.enabled }} apiVersion: autoscaling/v2 kind: HorizontalPodAutoscaler metadata: name: {{ include "helm-chart.name" . }} namespace: {{ .Values.application.namespace }} spec: scaleTargetRef: apiVersion: apps/v1 kind: Deployment name: {{ include "helm-chart.name" . }} minReplicas: {{ .Values.application.autoscaling.minReplicas }} maxReplicas: {{ .Values.application.autoscaling.maxReplicas }} metrics: {{- include "helm-chart.autoscalingconfiguration" . | indent 3 }} {{ end }}

Anything else we need to know?
