Describe the bug

I can't deploy the helm with the following values.yaml:

front:
  hostPort:
    enabled: false

  externalService:
    enabled: true
    type: ClusterIP

I get the following error:

Error: Service "mailu-front-ext" is invalid: spec.externalTrafficPolicy: Invalid value: "Local": may only be set when `type` is 'NodePort' or 'LoadBalancer'

Environment

• Kubernetes Platform Scaleway

Additional context

I have an existing nginx ingress as LoadBalancer with correct TCP service forwarding.
