"invalid object type" applying v1 NetworkPolicy with Calico

Describe the bug I get an error status with message invalid object type: networking.k8s.io/v1, Kind=NetworkPolicy when calling Kubectl.apply from io.kubernetes.client.extended.kubectl on a V1NetworkPolicy object loaded from YAML. This specifically happens when calling a minikube instance with the Calico networking plugin. If it's using the default Kindnet plugin (which now supports NetworkPolicy), there's no error.

Note that there's also no error when applying the same YAML file using the kubectl CLI.

Client Version 24.0.0

Kubernetes Version 1.32.0

Java Version Kotlin 2.1.0 on Java 17

To Reproduce

1. Start minikube with --cni=calico
2. Load YAML file containing a v1 NetworkPolicy object using io.kubernetes.client.util.Yaml
3. Call Kubectl.apply with that object.

Expected behavior NetworkPolicy object is applied (in this case, created) successfully.

Server (please complete the following information):

• OS: Linux (Debian testing)
• Environment: Local w/minikube
