I am trying to create a redis helm chart via a module within a github workflow. The problem seems to be in the helm-values.yaml file in the module.
It’s an error converting YAML to JSON: yaml.

I have a workflow in github that executes a command that terraform apply a module that is in another github repo, in this module I have a helm-values.yaml that looks like this:

architecture: standalone

fullnameOverride: ${redis_deployment_name}
auth:
  password: ${redis_admin_password}
# auth:
#   existingSecret: redis
#   existingSecretPasswordKey: redis-password

master:
  ${ indent(2, redis_affinity) }
  ${ indent(2, redis_nodeSelector) }
  ${ indent(2, redis_default_tolerations) }
  persistence:
    enabled: false
  resources:
    limits:
      cpu: 350m
      memory: 700Mi
    requests:
      cpu: 100m
      memory: 256Mi

pdb:
  enabled: true

# Explicit activation of Redis Stream
redisStreamEnabled: true

but I get this error:

 Error: ---> error converting YAML to JSON: yaml: line 19: did not find expected key architecture: standalone

I changed the manifest file to look like this:

## @param architecture; architecture. Allowed: `standalone` or `replication`
##
architecture: standalone

fullnameOverride: ${redis_deployment_name}
auth:
  password: ${redis_admin_password}
# auth:
#   existingSecret: redis
#   existingSecretPasswordKey: redis-password
master:
  ${ indent(2, redis_affinity) }
  ${ indent(2, redis_nodeSelector) }
  ${ indent(2, redis_default_tolerations) }
  persistence:
    enabled: false
  resources:
    limits:
      cpu: 350m
      memory: 700Mi
    requests:
      cpu: 100m
      memory: 256Mi
pdb:
  enabled: true

# Explicit activation of Redis Stream
redisStreamEnabled: true

But now i’m getting this error:

 Error: ---> error converting YAML to JSON: yaml: line 21: did not find expected key ## @param architecture; architecture. Allowed: `standalone` or `replication`

So i changed one more time to this:

---
# Parameter info: architecture. Allowed values: `standalone` or `replication`

architecture: standalone

fullnameOverride: ${redis_deployment_name}
auth:
  password: ${redis_admin_password}
# auth:
#   existingSecret: redis
#   existingSecretPasswordKey: redis-password

master:
  ${ indent(2, redis_affinity) }
  ${ indent(2, redis_nodeSelector) }
  ${ indent(2, redis_default_tolerations) }
  persistence:
    enabled: false
  resources:
    limits:
      cpu: 350m
      memory: 700Mi
    requests:
      cpu: 100m
      memory: 256Mi

pdb:
  enabled: true

# Explicit activation of Redis Stream
redisStreamEnabled: true

But now I get this error:

 Error: ---> error converting YAML to JSON: yaml: line 22: did not find expected key ---
│ # Parameter info: architecture. Allowed values: `standalone` or `replication`

Every time I change the code, I get errors related to the first line even if it is a comment.
I used **yamllint **to verify, the code works locally when i don’t call it as a module, when i do a terraform apply directly in the root module.
What seems to be the problem?
