HelmRelease not able to work with customresourcedefinition PostgresService

[akumari144088]

Describe the bug

HelmRelease not able to work postgres database. It doesnt process the code for customresourcedefinition PostgresService

Below is the chunk of the code for that crd.
patroni:
clusterName: {{default "patroni" .Values.patroni.clusterName}}
dcs:
type: {{ default "kubernetes" .Values.patroni.dcs.type }}
{{ if or (eq .Values.patroni.dcs.type "etcd3") (eq .Values.patroni.dcs.type "etcd") }}

Helm Release is not able to process this. It process it as syntax error. However this code is working fine the in environment but somehow helmrelease is not able to process it. It gives below error
YAML parse error on postgres-operator-chart/templates/cr.yaml: error converting YAML to JSON: yaml: line 27: found character that cannot start any token

Steps to reproduce

Install flux with gitrepsitory controllers and helmrelease controllers
Install postgres helm charts and try to install it with crd postgresservices

Expected behavior

It should run without failure and create the postgresservices customresourcedefintion

Hi, can you put code in code blocks? It will be easier to read. Can you provide the outputs of flux check and kubectl describe helmrelease

[akumari144088]

    clusterName: {{default "patroni" .Values.patroni.clusterName}}
    dcs:
      type: {{ default "kubernetes" .Values.patroni.dcs.type }}
      {{ if or (eq .Values.patroni.dcs.type "etcd3") (eq .Values.patroni.dcs.type "etcd") }}

can you also provide the .spec so I can reproduce this?

I see that you own the chart git repository. The issue here is with the chart. Maybe use helm lint? There is also https://github.com/helm/chart-testing for testing your chart.

@souleb It was not a syntax problem. There was problem in overrding values which is fixed now. But thanks for pointing me in right direction.

I have one other issue though. Its about dynamic manipulation of config map. Does HelmRelease doesnt allow it? Below is the config and error

data:
  security-configurations.tar.gz: |-
    {{- "\n" }}
    {{- .Files.Get "tar_archive.tar.gz" | b64enc | indent 4 }}
    ```
