Deploy Traefik with ArgoCD and additional values file

Question

I'm trying to install Traefik on a K8s cluster using ArgoCD to deploy the official Helm chart. But I also need it to us an additional "values.yml" file. When I try to specify in the Application yaml file what additional values file to use, it fails to file not found for it.

Here is what I'm using:

apiVersion: argoproj.io/v1alpha1
kind: Application
metadata:
  name: argo-traefik-chart
  namespace: argocd
spec:
  project: default
  source:
    path: traefik
    repoURL: https://github.com/traefik/traefik-helm-chart.git
    targetRevision: HEAD
    helm:
      valueFiles:
        - /traefik-values.yml
  destination: 
    server: https://kubernetes.default.svc
    namespace: 2195-leaf-dev-traefik
  syncPolicy:
    syncOptions:
      - CreateNamespace=true
    automated:
      prune: true
      selfHeal: true

Here is the traefik-value.yml file.

The traefik-values.yml file is in the same sub-directory as this file. I fire this of with kubectl apply -f but when I got to look at it in the Argo GUI, it shows an error. I'll paste the entire thing below, but it looks like the important part is this:

` failed exit status 1: Error: open .traefik-values.yml: no such file or directory

It's putting a period before the name of the file. I tried different ways of specifying the file: .traefik-values.yml and ./treafik-values.yml. Those get translated to:

: Error: open .traefik/.traefik-values.yml: no such file or directory

When I do a helm install using the exact same traefik-values.yml file, I get exactly what I expect. And when I run the Argo without the alternate file, it deploys but with out the needed options of course.

Any ideas?
