Add Aborts in virtualservice to specific prefixes

1

Hello,

My use case is to block the calls that are ending with “/audit” or “/heap”

I am using this config but it is throwing me an error saying “fault” is not recognized:

apiVersion: networking.istio.io/v1alpha3
kind: VirtualService
spec:
  gateways:
  - my-gateway
  hosts:
  - '*'
  http:
  - match:
    - uri:
        prefix: /heap
    fault:
      abort:
        percentage:
          value: 100
        httpStatus: 400

I dont want to send it to any destination. I just want istio to completely discard these call with a 400 error.

What should I change to make it working ?
