Client-go: dynamic client requested resource not found

[AdheipSingh]

Trying to access istio crds using dynamic client, each time i access i get this error

2020/01/21 19:44:10 the server could not find the requested resource

Here is the code snippet i am trying to run

loggingRes := schema.GroupVersionResource{
        Group:    "networking.istio.io",
        Version:  "v1beta1",
        Resource: "virtualservices",
    }

    client := utils.GetKubeClientset()

    result, err := client.Resource(loggingRes).Namespace("default").Get("reviews", metav1.GetOptions{})
    if err != nil {
        log.Printf("%s", err.Error())
    }

When i switch GVR kind to deployments or native kubernetes GVR it works. Any help would be appreciated.
Here are the version i am running

is that the correct virtualservice API version? the documentation I see is v1alpha3 (e.g. https://istio.io/docs/reference/config/networking/virtual-service/)

What does kubectl api-versions output?

[AdheipSingh]

oh sorry it was a typo for istio, it worked for istio but not for other resources

loggingRes := schema.GroupVersionResource{
        Group:    "logging.banzaicloud.io",
        Version:  "v1beta1",
        Resource: "logging",
    }

The CRD is cluster scoped

[liggitt]

Verify you are using the correct resource name (kubectl api-resources will show all available resources, and you must use the plural resource name when constructing the dynamic client)

The CRD is cluster scoped

For cluster-scoped resources, omit the .Namespace("...") call

[AdheipSingh]

plural was the issue, i was not aware of that. Silly....

Thanks a ton @liggitt . Much Appreciated
