• I've included steps to reproduce the bug.
• I've pasted the output of argocd version.

Describe the bug

When application manifest is applied and later synced logs from argocd-repo-server return

"time=\"2022-12-20T10:57:41Z\" level=warning msg=\"not generating manifests as path and chart fields are empty\" source=\"&ApplicationSource{RepoURL:git@github.com:myrepo/helm-test.git,Path:,TargetRevision:lukas-testing,Helm:nil,Kustomize:nil,Directory:nil,Plugin:nil,Chart:,Ref:values,}\"\n"

To Reproduce

Apply application manifest that has 2 sources

application.yaml

apiVersion: argoproj.io/v1alpha1
kind: Application
metadata:
  name: tempo-vulture
  namespace: argocd
spec:
  project: default
  syncPolicy:
    automated:
      prune: true
      selfHeal: true
  destination:
    server: https://kubernetes.default.svc/
    namespace: lukas
  sources:
  - repoURL: 'https://grafana.github.io/helm-charts'
    chart: tempo-vulture
    targetRevision: 0.2.1
    helm:
      valueFiles:
      - $values/tempo-vulture.yaml
  - repoURL: 'git@github.com:myrepo/helm-test.git'
    targetRevision: lukas-testing
    ref: values

tempo-vulture.yaml

replicas:2

and perform Sync

Expected behavior

this shouldn't be happening as second source only specifies values in the git repo.

I think we should remove this log or just change the logging level to Debug instead of Warn..
