# oc create -f egress.json -n a1
{
    "kind": "EgressNetworkPolicy",
    "apiVersion": "v1",
    "metadata": {
        "name": "default"
    },
    "spec": {
        "egress": [
            {
                "type": "Allow",
                "to": {
                    "cidrSelector": "10.66.128.0/24"
                }
            },
            {
                "type": "Deny",
                "to": {
                    "cidrSelector": "10.66.140.0/24"
                }
            }
        ]
    }
}
3. Delete the project
4. Check the egressnetworkpolicy
[root@master ~]# oc get egressnetworkpolicy --all-namespaces
NAMESPACE   NAME
a1          default

5. Delete the egressnetworkpolicy by admin
# oc delete egressnetworkpolicy default -n a1



Actual results:
[root@master ~]# oc delete egressnetworkpolicy default -n a1
Error from server: namespaces "a1" not found


Expected results:
The egressnetworkpolicy can be deleted successfully
