I set ippool, but I still get an error when I execute the command?

@xuegao321 It looks like subctl is not able to read the ippools here - https://github.com/submariner-io/submariner-operator/blob/47268fb9eb09e8478c139b1c1d681176110f1bf7/pkg/subctl/cmd/diagnose/cni.go#L130

Can you share the output of one of your ippools. I'd like to compare it with the GVR we use while listing the ippools.

    calicoGVR = schema.GroupVersionResource{
        Group:    "crd.projectcalico.org",
        Version:  "v1",
        Resource: "ippools",
    }
