Helm rendering fails on metrics service even if i don't need it

Welcome!

• Yes, I've searched similar issues on GitHub and didn't find any.
• Yes, I've searched similar issues on the Traefik community forum and didn't find any.

What version of the Traefik's Helm Chart are you using?

20.7.0

What version of Traefik are you using?

v2.9.6

What did you do?

I don't have .Values.metrics.prometheus.service set in my values file (so it should be disabled by default)

I execute helm template --name-template=[name that contains more than 50 chars] .

What did you see instead?

Error: execution error at (ingress-traefik/charts/traefik/templates/service-metrics.yaml:7:6): ERROR: Cannot create a metrics service when name contains more than 50 characters

What is your environment & configuration?

I use the default Traefik values file + some override but not on for the metrics part.

Additional Information

If i move the

{{- if .Values.metrics.prometheus }}
{{- if .Values.metrics.prometheus.service }}
{{- if (and (.Values.metrics.prometheus.service).enabled (not .Values.hub.enabled)) -}}

before

{{- $fullname := include "traefik.fullname" . }}
{{- if ge (len $fullname) 50 }}
  {{- fail "ERROR: Cannot create a metrics service when name contains more than 50 characters" }}
{{- end }}

on https://github.com/traefik/traefik-helm-chart/blob/master/traefik/templates/service-metrics.yaml , then it works again.
