HelmRepository with OCI urls have no status

[defenestration]

We updated flux 2.1.x to flux 2.2.3. Some of the kube-state-metrics alerts we had started triggering. I was able to make some changes for notification resources but we have some OCI helm charts in use that have no status reported in the kubernetes object, giving kube-state-metrics nothing to scrape a status from apparently.

Other helm repositories using https are fine, and have a fully defined status: field.

❯ flux get sources helm -A
NAMESPACE       	NAME                            	REVISION       	SUSPENDED	READY	MESSAGE
...
flux-system     	azure-oci                       	               	False    	True 	Helm repository is Ready
flux-system     	ww-gitops                       	               	False    	True 	Helm repository is Ready
ingress-nginx   	ingress-nginx                   	sha256:9c0f8ad3	False    	True 	stored artifact: revision 'sha256:9c0f8ad3'

We use pretty much the same kube-metrics-config as here https://github.com/fluxcd/flux2-monitoring-example/blob/main/monitoring/controllers/kube-prometheus-stack/kube-state-metrics-config.yaml

Heres a helm repo we use for the weaveworks dashboard as a public example. Note that status field is empty which seems to be the problem.

❯ k get helmrepository -n flux-system ww-gitops -o yaml

Would appreciate some advise here. Probably going to be disabling the HelmRepository monitoring for now as a workaround.

Hi, objects that don't have any status are assumed to be ready as they have nothing to do. Their existence can be assumed as they are ready. In this case, HelmRepository of type OCI are static objects. They are not reconciled any more.
#9 may be relevant here, at least the PR description. I believe that the corresponding grafana panel for readiness of objects is configured to show not ready only when the status says Ready=False explicitly.
Also, refer fluxcd/source-controller#1249 for more details about this change.
