Hello @EnochTheWise, can you elaborate on what the issue is with the cert-manager-webhook-pdns? Can you provide logs from the cert-manager-webhook-pdns pod?

As an aside, I would say your issue in the kube-apiserver logs is with the fintechiq custom resource and not anything related to this project.

Hello @EnochTheWise, can you elaborate on what the issue is with the cert-manager-webhook-pdns? Can you provide logs from the cert-manager-webhook-pdns pod?

Hello @zachomedia , i have same issue as @EnochTheWise.
Logs from pod is

meanwhile cluster not have this api-resources:

root@mycluster-master-01 ~ # kubectl api-resources --verbs=list | grep -i flow
flowschemas                     flowcontrol.apiserver.k8s.io/v1beta1   false    FlowSchema
prioritylevelconfigurations     flowcontrol.apiserver.k8s.io/v1beta1   false    PriorityLevelConfiguration

so i think ACME resolver try to work with not existed resources
Is it possible to switch v1beta2.flow... to v1beta1.flow...?

googled that this error not affects anything.

@EnochTheWise / @ABess-Flant Can you share what version of Kubernetes you're running? I will see if I can reproduce the issue. There is nothing in my code that is loading those resources, so it might be something with the Kubernetes libraries.

k8s version 1.21.14.
But i suppose that some libraries ( maybe go lib ) queries all know versions and print those, which can't find.
I successfully set this webhook up, so this error not affect anything.

A some addition.
ApiService is exist:

$ k get apiservices v1alpha1.v1alpha1.fintechiq
NAME               SERVICE                                  AVAILABLE   AGE
v1alpha1.fintechiq   cert-manager/cert-manager-webhook-pdns   True        64d

We have same issue :

E1218 13:26:46.615437       1 controller.go:102] loading OpenAPI spec for "v1alpha1.acme.zacharyseguin.ca" failed with: failed to download v1alpha1.acme.zacharyseguin.ca: resource not found

This is not breaking any functionality but annoying to see those logs. Also I don't know what is real impact on kube-apiserver.
k8s : v1.29.5
cert-manager-webhook-pdns : v2.5.1
