Describe the bug

After successfully deploying an APP for prometheus using a multi source application as per TheDocs manual Sync's of the app via cli or UI result in an error of repo not found. The resource were previously deployed in the cluster, we are retroactively tracking them in argo now. Argo sync's green and is able to discover all resources upon app creation. This seems like it is aware of the chart and able to pull the chart at least initially, but I may be confused as to how argo handles things in this scenario.

I have tried adding the helm repo url to my list of connected repos, resulting in a successful add as well.

To Reproduce

Create an app with the following definition, pointing to a valid git repo with a values.yaml file.

kind: Application
metadata:
  name: prometheus
  namespace: utilities
spec:
  project: utils
  destination:
    server: https://kubernetes.default.svc
    namespace: monitoring
  syncPolicy:
    automated: {}
  sources:
    - chart: prometheus
      repoURL: 'https://prometheus-community.github.io/helm-charts'
      targetRevision: 25.17.0
      helm:
        valueFiles:
        - $values/prometheus/values.yml
    - repoURL: 'git@yourgitdomain.com/repo.git'
      targetRevision: HEAD
      ref: values`

Expected behavior

Sync should be successful
