Argocd manager not able to parse yaml wrapped in a helm flow control

What would you like help with?

I think I found a bug

How are you running Renovate?

Hi everyone,
we recently ran into a small issue, where Renovate is not able to parse argocd yaml-files, that are wrapped in a helm flow control like in the following example.

{{- if .Values.enabled }}
apiVersion: argoproj.io/v1alpha1
kind: Application
spec:
  source:
    chart: kube-state-metrics
    repoURL: https://prometheus-community.github.io/helm-charts
    targetRevision: 2.4.1
{{- end }}

It looks like the current schema configuration can not handle this type of yaml-file, which leads to a parsing failure where the file is skipped silently (only visible via LOG_LEVEL=debug).

Logs (if relevant)

       }

This is not a valid yaml file, and not a bug

[viceice]

it's not a bug. it's simply not supported.

it should be easy to support, because we've already a function to strip go templates language before parsing the yaml.

Hi @viceice,
thanks for the hint. I've created a PR #27766.
