nginx.ingress.kubernetes.io/server-snippet annotation contains invalid word location-CodePudding

I am new to kubernetes and using AWS EKS cluster 1.21. I am trying to write the nginx ingress config for my k8s cluster and blocking some request using server-snippet. My ingress config is below

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: abc-ingress-external
  namespace: backend
  annotations:
    nginx.ingress.kubernetes.io/rewrite-target: /
    kubernetes.io/ingress.class: nginx-external
    nginx.ingress.kubernetes.io/server-snippet: |
       location = /ping {
         deny all;
         return 403;
       }
spec:
  rules:
  - host: dev-abc.example.com
    http:
      paths:
      - backend:
          service:
              name: miller
              port:
                number: 80
        path: /
        pathType: Prefix

When I apply this config, I get this error:

for: "ingress.yml": admission webhook "validate.nginx.ingress.kubernetes.io" denied the request: nginx.ingress.kubernetes.io/server-snippet annotation contains invalid word location

I looked into this and got this is something related to annotation-value-word-blocklist. However i don't know how to resolve this. Any help would be appreciated.
