This is my Kustomise folder structure, i have kept the istio in base. base.kustomisation yaml has istio.yaml reference.

When i try to build in dev or prod ( kustomise build . ) in locally ,I get the below error

this is giving below error -
webhooks.clientConfig.service ignored in mutation attempt

When i remove the istio.yaml file and run command kustomise build . in local it works fine.

istio.yaml.txt

Note: Kustomize need to be apply cluster via flux-cd.
