GatewayClass does not recognize 1.3 CRDs

[swilkTUDA]

When installing haproxy unified gateway (version: ) in our cluster the installed gatewayclass object lists

 - lastTransitionTime: "2026-02-22T21:42:58Z"
   message: Gateway API CRD versions are not supported. Please install version v1.2, v1.3
   observedGeneration: 1
   reason: UnsupportedVersion
   status: "False"
   type: SupportedVersion

The CRDs were installed from https://github.com/kubernetes-sigs/gateway-api/releases/download/v1.3.0/standard-install.yaml
The same error message is shown when installing gateway-api in version 1.2.1

The gatewayclass installed is:

apiVersion: gateway.networking.k8s.io/v1
kind: GatewayClass
metadata:
     name: gateway-internal
spec:
     controllerName: gate.haproxy.org/hug

Hi @swilkTUDA
Can you check if for example you do not have several versions of Gateway API CRDs installed.
For example pasting the output of:

kubectl get crds -o custom-columns=\
NAME:.metadata.name,\
VERSIONS:.spec.versions[*].name,\
BUNDLE:".metadata.annotations.gateway\.networking\.k8s\.io/bundle-version",\
CHANNEL:".metadata.annotations.gateway\.networking\.k8s\.io/channel" \
| grep "gateway.networking.k8s.io"

Can you also see if you have any error in logs ?
