I am trying to install Knative on my GKE cluster. I followed the Knative website to do it. However, Knative Serving can't be installed due to the following error:

Failed to pull image "gke.gcr.io/istio/proxy_init:1.2.10-gke.1": rpc error: code = Unknown desc = Error response from daemon: manifest for gke.gcr.io/istio/proxy_init:1.2.10-gke.1 not found: manifest unknown: Failed to fetch "1.2.10-gke.1" from request "/v2/istio/proxy_init/manifests/1.2.10-gke.1".

Do you know how to solve this ?

Regards,
