I’m trying to set up an Argo CD ApplicationSet where I want to enable auto-sync for the develop environment and disable it for the prod environment. Here’s what I have so far:

apiVersion: argoproj.io/v1alpha1
kind: ApplicationSet
metadata:
  name: my-application-deployment
spec:
  goTemplate: true
  goTemplateOptions: ["missingkey=error"]
  generators:
  - list:
      elements:
      - env: develop
        namespace: dev-my-service
        sync: true
      - env: prod
        namespace: my-service
        sync: false
  template:
    metadata:
      name: 'my-service-{{.env}}'
    spec:
      project: default
      source:
        repoURL: 'https://example.com/my-repo.git'
        targetRevision: develop
        path: 'my-service'
        helm:
          valueFiles:
          - 'values-{{.env}}.yaml'
      destination:
        name: in-cluster
        namespace: '{{.namespace}}'
      syncPolicy:
        syncOptions:
          - CreateNamespace=true
        {{- if .sync }}
        automated:
          prune: true
          selfHeal: true
        {{- end }}

However, it seems that Argo CD doesn’t support conditions in go-template for the syncPolicy field. When I try to apply this manifest, I get an error:

error splitting YAML to string: failed to unmarshal manifest: error converting YAML to JSON: yaml: line 36: could not find expected ':'
Thanks in advance!
