Describe the bug

I configured an application containing a Git source with an umbrella Helm chart that has an OCI dependency from DockerHub. Despite adding the credentials for our DockerHub Pro account to the ArgoCD repository configuration, ArgoCD does not use them, leading to pull rate limit errors.

To Reproduce

1. Create a simple ArgoCD Application containing a git source
2. Create an umbrella chart with a docker oci helm chart dependency. In my case:

      - name: mongodb
        version: "16.4.0"
        repository: "oci://registry-1.docker.io/bitnamicharts"
   

3. Add the docker OCI repository to ArgoCD
4. Start a lot of syncs

Expected behavior
The repository from ArgoCD should also be used in helm dependencies.

My code

Repository

apiVersion: v1
kind: Secret
metadata:
  name: dockerhub-bitnamicharts
  namespace: argocd
  labels:
    argocd.argoproj.io/secret-type: repository
stringData:
  name: dockerhub-bitnamicharts
  type: helm
  url: registry-1.docker.io/bitnamicharts
  username: xxx
  password: xxx
  enableOCI: "true"

Application

{{- $service := .Values.services.mongodb }}
{{- if $service.enabled }}
apiVersion: argoproj.io/v1alpha1
kind: Application
metadata:
  name: mongodb
  namespace: argocd
spec:
  project: services
  destination:
    server: "https://kubernetes.default.svc"
    namespace: services
  syncPolicy:
    syncOptions:
    - CreateNamespace=true
  sources:
    - repoURL: https://git.xxx.de/xxx/portal/argocd-deployment.git
      path: charts/services/mongodb/
      targetRevision: {{ include "xxx.appTargetRevision" . }}
      helm:
        releaseName: mongodb
        passCredentials: true
        valueFiles:
          - /vars/base/services/mongodb.yaml
          - /vars/{{ .Values.bootstrapEnvironment }}/services/mongodb.yaml
{{ end }}

Chart.yaml

[...]
dependencies:
- name: mongodb
  version: "16.4.0"
  repository: "oci://registry-1.docker.io/bitnamicharts"
