unable to update an old helm installation using --reuse-values

[jkremser]

when trying to update an existing helm chart release of kedify agent in version v0.5.0

by running:

helm upgrade --install kedify-agent kedifykeda/kedify-agent --version v0.7.1 \
  --namespace keda \
  --reuse-values

i got:

Error: UPGRADE FAILED: template: kedify-agent/templates/cr-install/cr.yaml:20:3: executing "kedify-agent/templates/cr-install/cr.yaml" at <tpl ($.Files.Get "files/crs/default-kedifyconfig.yaml") $>: error calling tpl: error during tpl function execution for "apiVersion: install.kedify.io/v1alpha1\nkind: KedifyConfiguration\nmetadata:\n  name: kedify\n  namespace: {{ .Release.Namespace }}\nspec:\n  clusterName: {{ .Values.clusterName }}\n  {{- if .Values.agent.cloudAccountID }}\n  cloudAccountID: \"{{ .Values.agent.cloudAccountID }}\"\n  {{- end }}\n  kedaInstallations:\n  - name: {{ .Release.Namespace }}\n    namespace: {{ .Release.Namespace }}\n    {{- if eq (include \"kedify-agent.featureEnabled\" (list . \"multitenantKEDAEnabled\")) \"true\" }}\n    multitenancy: {}\n    {{- end }}\n{{ toYaml .Values.agent.kedifyConfiguration | indent 4 }}\n": template: gotpl:14:15: executing "gotpl" at <include "kedify-agent.featureEnabled" (list .

ah, not an issue. That's a described behavior of --reuse-values (it doesn't apply the existing values over the default values from the new helm chart)

using

    --reset-then-reuse-values

instead worked.
