Error while updating iap-ingress for custom domains

When following the instructions for using custom domains (https://www.kubeflow.org/docs/guides/gke/custom-domain/), I ran into this error:

ks apply default -c iap-ingress

Looks like this is already opened as #1145

I think the work around is to delete the existing components before updating them.
