**Issue with Middleware Configuration Using Plugin AuthCookie in Traefik (Kubernetes CRD)**

Hi Traefik Community,

I'm currently experiencing an issue while configuring a middleware that utilizes the **AuthCookie** plugin in Traefik with Kubernetes CRD. I have carefully followed the documentation and created the required middleware, but I keep encountering the following error:

```auto
invalid middleware "xxxx-xxxx-xxxx-authcookie@kubernetescrd" configuration: invalid middleware type or middleware does not exist

```

I’m not sure if this helps, but here’s my **Helm `values.yaml`** configuration:

```auto

  replicas: 1

  resources:
    requests:
      cpu: "100m"
      memory: "512Mi"
    limits:

```

Additionally, I have developed and published the **AuthCookie** middleware plugin, which can be found here:  
[authcookie](https://plugins.traefik.io/plugins/67a9dc48732aa22ce948f50a/authcookie)

I would appreciate any insights or guidance on resolving this issue. Thanks in advance for your help!

Best,
