Flux Helm Install Duplicate Values

[Josh-Tracy]

The issue

When I run helm install -n harness harness charts/harness-0.26.9.tgz -f values.yaml myself with my values.yaml file the helm chart deploys as expected.

When I install with FluxCD Helm Controller I get the following error:

  Warning  InstallFailed  22s (x11 over 15m)  helm-controller  Helm install failed for release harness/harness-harness with chart harness@0.26.9+abc4d8b4f8b3: error while running post render on files: map[string]interface {}(nil): yaml: unmarshal errors:

What I expect to happen

Install with FluxCD HelmRelease CRD should be possible.

My FluxCD yaml

I removed the values for sensitive reasons. I have tried with with the below inline values: and also ValuesFrom with a configMap. Both result in the same error.

apiVersion: helm.toolkit.fluxcd.io/v2beta2
kind: HelmRelease
metadata:
  name: harness
  namespace: harness
spec:
  chartRef:
    kind: OCIRepository
    name: zot-harness
    namespace: harnes
  interval: 10m
  values:
    xxxxxxxxx
targetNamespace: harness

Additional Info

cat harness/charts/code/charts/code-api/templates/config.yaml looks to be the template that is handling the creation of these duplicate values.

I created a rendered.yaml helm template harness harness -f ../values.yaml > rendered.yaml and observed the following with cat rendered.yaml | grep BASEURL

HARNESS_SERVICES_ACL_CLIENT_BASEURL: ""
  HARNESS_SERVICES_AUDIT_CLIENT_BASEURL: ""

I was able to fix the issue by editing the chart harness/charts/code/charts/code-api/values.yaml and commenting out the offending keys with values of "". I do not believe that should be necessary though. This should work out of the box.

Thanks @Josh-Tracy for reporting the issue. We will fix it in the upcoming release.
