How to sync the helm chart dir without Chart.yaml

[yidongw]

helm template or helmfile template will generate directories and charts without Chart.yaml

for example
helmfile template --output-dir-template $(pwd)/gitops//{{.Release.Namespace}}
will generate the following directories structure.

gitops/traefik/
└── traefik
    └── templates
        ├── dashboard-hook-ingressroute.yaml
        ├── deployment.yaml
        ├── rbac
        │   ├── clusterrole.yaml
        │   ├── clusterrolebinding.yaml
        │   └── serviceaccount.yaml
        └── service.yaml

3 directories, 6 files

there is no Chart.yaml

So when I create an application chart like this

apiVersion: argoproj.io/v1alpha1
kind: Application
metadata:
  name: traefik
  finalizers:
  - resources-finalizer.argocd.argoproj.io
spec:
  destination:
    server: https://kubernetes.default.svc
    namespace: traefik
  project: default
  source:
    path: gitops/traefik/traefik/
    repoURL: git@gitlab.com:org/me/helm-charts.git
    targetRevision: HEAD
  syncPolicy:
    automated:
      prune: true
      selfHeal: true

traefik will not be properly installed.

I have been googling around and trying to find the answer but I couldn't find it.

Can argocd support installing the sub-charts without Chart.yaml? Or do I have to manually create that one by one?
