'error: resource mapping not found || make sure CRDs are installed first

error: resource mapping not found for name: "ingress-srv" namespace: "" from "ingress-srv.yaml": no matches for kind "Ingress" in version "networking.k8s.io/v1beta1" ensure CRDs are installed first

I am new to Kubernetes, I was setting up ingress nginx on minikube and it installed successfully but when I try to run using kubectl apply -f filename it gives above error

here is the code filename: ingress-srv.yaml

apiVersion: networking.k8s.io/v1beta1
kind: Ingress

  name: ingress-srv
  annotations:
    kubernetes.io/ingress.class: nginx
