Hi, I am able to deploy it on argocd using the following manifest:

apiVersion: argoproj.io/v1alpha1
kind: Application
metadata:
  annotations:
    argocd.argoproj.io/sync-wave: "2"
  name: n8n
  namespace: argocd
  finalizers:
    - resources-finalizer.argocd.argoproj.io
spec:
  project: gke-cluster
  source:
    chart: n8n
    repoURL: 8gears.container-registry.com/library
    targetRevision: 0.25.2
    helm:
      releaseName: n8n
      valueFiles:
        - secrets+age-import:///helm-keys/key.txt?https://raw.githubusercontent.com/user/argocd/n8n/secrets.enc.yaml
      valuesObject:
        fullnameOverride: n8n
        extraEnv:
          WEBHOOK_URL: https://<the-n8n-address>
        autoscaling:
          enabled: true
          minReplicas: 2
          maxReplicas: 5
          targetCPUUtilizationPercentage: 60
        scaling:
          enabled: true
        redis:
          enabled: true
        service:
          type: ClusterIP
          port: 80
  destination:
    name: in-cluster
    namespace: n8n
  syncPolicy:
    automated:
      selfHeal: true

Please notice that on my manifest, I encrypted the n8n secrets using SOPS + rage. The encrypted file will be executed as helm values to the chart.
