^{Originally posted by karthik1710 January 4, 2024} Hi All,

I'm trying deploy a helm chart with custom values ref: from private git repo. Both helm chart and git repo are private and repositories are already added in argocd.

Below is my argocd setup,

argocd: v2.9.3+6eba5be
  BuildDate: 2023-12-01T23:24:09Z
  GitCommit: 6eba5be864b7e031871ed7698f5233336dfe75c7
  GitTreeState: clean
  GoVersion: go1.21.4
  Compiler: gc
  Platform: linux/amd64
argocd-server: v2.9.3+6eba5be
  BuildDate: 2023-12-01T23:05:50Z
  GitCommit: 6eba5be864b7e031871ed7698f5233336dfe75c7
  GitTreeState: clean
  GoVersion: go1.21.3
  Compiler: gc
  Platform: linux/amd64
  Kustomize Version: v5.2.1 2023-10-19T20:13:51Z
  Helm Version: v3.13.2+g2a2fb3b
  Kubectl Version: v0.24.2
  Jsonnet Version: v0.20.0

My application.yaml

apiVersion: argoproj.io/v1alpha1
kind: Application
metadata:
  name: fr-eb-mongodb-dev
spec:
  destination:
    name: ''
    namespace: fr-mongodb-dev
    server: 'https://kubernetes.default.svc'
  sources:
  - repoURL: 'https://gitlab.com/api/v4/projects/xxxx/packages/helm/stable'
    chart: mongodb
    targetRevision: 1.0.0
    helm:
      valueFiles:
      - $values/custom-value/values-fr.yaml
  - repoURL: 'https://gitlab.com/xxxx/eb-xxxx/exxx.git'
    targetRevision: custom-values
    ref: values
  project: default
  syncPolicy:
    automated:
      prune: false
      selfHeal: false

In the application.yaml, I trying to deploy private helm chart with custom values from git repository. But after deployment I could see Argocd is not getting custom values from the referred repo.

Thanks in advance. :raised_hands:

@ishitasequeira Can you help me in this? Thanks

I can confirm the issue. Just happening for a multi-sources app, and on different argocd versions: v2.9.3 and v2.8.5. Also happens with the repository and credentials template. How should we proceed with this issue?

Exact error: Failed to load target state: failed to generate manifest for source 1 of 2: rpc error: code = Unknown desc = failed to get git client for repo https://github.com/xxx-org/gitops-repo'

Also, we've tried to downgrade argocd to v2.7.8 and use ssh auth method, but no luck. Still getting the same issue.

Thanks @karthik1710 and @stepa-ict for raising the issue. I will try reproducing the issue on my end.

@ishitasequeira Do you have any info regarding this issue? It becomes very important. We've switched completely to multi-source apps, so this is a huge problem. Thanks for understanding. If we can help anyhow, please let us know.

Apologies for a delayed response. I tried reproducing the issue, and was able to see an error when used chart field. Try using path field instead. Below example worked for me and should resolve the issue you are seeing.

sources:
  - repoURL: '[email protected]:ishitasequeira/multi-source-test.git'
    path: helm-guestbook
    targetRevision: main
    helm:
      valueFiles:
        - $values/values-guestbook.yaml
  - repoURL: '[email protected]:ishitasequeira/multi-source-values.git'
    targetRevision: main
    ref: values
