TraefikService configuration not working with scaled down backend service

Traefik Traefik v2
1

Below is the TraefikService I am using:

apiVersion: traefik.containo.us/v1alpha1
kind: TraefikService
metadata:
  name: {{ .Values.name }}
  namespace: {{ .Values.namespace }}
spec:
  weighted:
    services:
    - name: {{ .Values.name }}
      port: 8000
      serversTransport: {{ .Values.name }}
      weight: 100
    - name: {{ .Values.name }}-baseline
      port: 8000
      serversTransport: {{ .Values.name }}
      weight: 0
    - name: {{ .Values.name }}-canary
      port: 8000
      serversTransport: {{ .Values.name }}
      weight: 0

Above is referenced from ingressRoute:

spec:
  entryPoints:
  - web
  routes:
  - kind: Rule
    match: Host(`{{ .Values.hostName }}`) && PathPrefix(`/`)
    services:
    - kind: TraefikService
      name: {{ .Values.name }}
      namespace: {{ .Values.name }}

In traefikService, the backend services with weight zero are scaled down and are only scaled up when the weight is changed to non-zero.
However, when I tested the request, I received 404 and could not see any service or router in the access log of Traefik for the request. When I scale backend services with weight zero up, the request works fine and returns 200.

I would like to know if this is the only way to avoid 404, i.e., have at least 1 replica of the backend service even if the weight is zero for that service.

Thanks
