argo-cd: unsupported HPA GVK: autoscaling/v2

Checklist:

I’ve searched in the docs and FAQ for my answer: https://bit.ly/argocd-faq.
I’ve included steps to reproduce the bug.
I’ve pasted the output of argocd version.

When I try to create an app using HPA apiVersion: autoscaling/v2beta2 the follow error is returned:

ComparisonError

unsupported HPA GVK: autoscaling/v2, Kind=HorizontalPodAutoscaler

SyncError

Failed sync attempt to fdc308aba08fbf3fc08b6d2870fc9acb70d9f09b: ComparisonError: unsupported HPA GVK: autoscaling/v2, Kind=HorizontalPodAutoscaler (retried 5 times).

To Reproduce

I used a typical HPA definition file:

apiVersion: autoscaling/v2
kind: HorizontalPodAutoscaler
metadata:
  name: test
spec:
  scaleTargetRef:
    apiVersion: apps/v1
    kind: Deployment
    name: test
  minReplicas: 1
  maxReplicas: 2
  metrics:
    - type: Resource
      resource:
        name: cpu
        target:
          type: Utilization
          averageUtilization: 50

If I use apiVersion: autoscaling/v2beta2 Argo CD works perfectly. But this apiVersion is deprecated in Kubernetes v1.23+ and unavailable in v1.26+.

IMPORTANT: When I apply the above definition using kubectl works fine (I’m using Kubernetes v1.23.5).

Expected behavior

I would like to apply HPA definition using apiVersion: autoscaling/v2.

Version

$ kubectl exec -it -n argocd deployment/argocd-server -- argocd version

Was seeing this issue with ArgoCD 2.1.x with autoscaling/v2, and upgrading to 2.5.5 via https://raw.githubusercontent.com/argoproj/argo-cd/v2.5.5/manifests/install.yaml resolved it immediately. (Kubernetes: EKS 1.24)

I confirm autoscaling/v2 resources are synced correctly with Argo CD v2.4.0. This ticket can be closed

a workaround we use for disabling health check for the HPA

resource.customizations: |-
      autoscaling/HorizontalPodAutoscaler:
        health.lua: |
          hs = {}
          hs.status = "Healthy"
          hs.message = "Ignoring HPA Health Check"
          return hs

I have this issue with ArgoCD 2.2.2 and autoscaling/v1. Hpa works fine:

HPA object is running well.
It scales when the load is happening.

So only one issue here, in Argo in events I see that it’s no healthy with the message: unsupported HPA GVK: autoscaling/v2, Kind=HorizontalPodAutoscaler. But I am using autoscaling/v1, strange…

Should we consider reopen the issue given 2.4.0 does not seem fix it based on several comments above?

Is there any progress or workaround?
