Helm translates curly braces {} into normal braces [] when passing value from values.yaml to chart

Output of helm version:

I have a helm chart that creates the following kubernetes secret

apiVersion: v1
kind: Secret
metadata:
  name: {{ .Values.kubernetes.appName }}conf
  namespace: {{ .Values.kubernetes.namespace }}
stringData:
  ConnectionStrings__SqlServerDb: Server={{ .Values.app.SqlHost }}; Database={{ .Values.app.SqlDatabase }}; User ID={{ 
  .Values.app.SqlUsername }}; password={{ .Values.secrets.SqlPassword }}; Application Name={{ 
  .Values.kubernetes.appName }}; TrustServerCertificate=true;

the value of the password in enclosed in curly braces e.g {SuperSecretPassword} which at the end gets translated by helm to [SuperSecretPassword] (with normal braces)

I tried escaping and quoting the value in different ways, but nothing seems to work keeping the curly braces in the final value

the only way I managed to get it working was to put the password directly in the secret yaml
password={SuperSecretPassword}

Any ideas how I can make helm ignore the special characters and mainly not translate {} into []?

here some of the escaping and quoting attempts that I did
password={{ .Values.secrets.SqlPassword | quote }} --> "[SuperSecretPassword]"
password={{ toString .Values.secrets.SqlPassword }} --> [SuperSecretPassword]
password="{{ .Values.secrets.SqlPassword }}" --> "[SuperSecretPassword]"
I also tried enclosing the whole ConnectionStrings__SqlServerDb value in ""

And none of the above seem to work

one workaround is to base64 encode the secret when you pass it to the helm kubernetes template and decode it inside the template itself
password={{ .Values.secrets.SqlPassword | b64dec }}

I suspect your values look like?:

secrets:
  SqlPassword: {SuperSecretPassword}

You need to quote SqlPassword: "{SuperSecretPassword}", as curly branches in yaml denote a map. Which is rendered as: password=map[supersecret:<nil>]
