Describe the bug

Get the following error when syncing a Helm chart:

ComparisonError: Failed to compare desired state to live state: failed to calculate diff: error calculating structured merge diff: error calculating diff: error while running updater.Apply: converting (v2.HorizontalPodAutoscaler) to (v1.HorizontalPodAutoscaler): unknown conversion

To Reproduce

Helm repo: https://istio-release.storage.googleapis.com/charts Chart: istiod Version: 1.16.7

This issue happened when I was migrating a Helm managed chart to ArgoCD, to emulate the situation:

1. Use helm install directly
2. Create an ArgoCD application for the same chart

Expected behavior

ArgoCD adopts the existing resources from Helm.

Version

v2.8.6

Try updating argocd version to the at least 2.10.

Try updating argocd version to the at least 2.10.

In #11136 you said you were using 2.10.5 and it still had this issue, no?

ArgoCD versions 2.10 and below have reached EOL. Can you upgrade and tell us if the issue is still present, please?
