When deploying an application from RHACM GUI and adding a route to access the service which runs on the eks cluster, we get an error:
        route.openshift.io/v1: the server could not find the requested resource

Checking the apiresource 

[docker@localhost eks]$ oc get route
error: the server doesn't have a resource type "route"

[docker@localhost eks]$ oc api-resources  | grep route
[docker@localhost eks]$ 

On the ROSA cluster:
docker@localhost rosa]$ oc api-resources | grep route
routemonitors                                              monitoring.openshift.io/v1alpha1                true         RouteMonitor
egressrouters                                              network.operator.openshift.io/v1                true         EgressRouter
routes                                                     route.openshift.io/v1                           true         Route
[docker@localhost rosa]$ date

And I able to add the route to the application.

1.  Create an EKS cluster
2.  Run the oc commands on the cluster
3.  oc get route fails.
