When I'm running following code:

minikube addons enable ingress

I'm getting following error:

So I had some bug issue in my PC. So, i reinstall minikube. After this when I use minikube start and all want fine. But when i enable ingress then the above error was showing.

And when i run skaffold dev the following error was showing:

Warning: extensions/v1beta1 Ingress is deprecated in v1.14+, unavailable in v1.22+; use networking.k8s.io/v1 Ingress
