Helm chart identifies numeric string as a number when creating a namespace

Question

I am trying to create a helm deployment where one of the templates is creating a namespace as below

apiVersion : v1
kind : Namespace
metadata :
  name : "{{ .Values.productId }}"

I am passing the value for the productId in values file as follows:

productId: "32345"

I get the following error when I do helm install/upgrade

Error: unable to build kubernetes objects from release manifest: unable to decode "": json: cannot unmarshal number into Go struct field ObjectMeta.metadata.namespace of type string helm.go:84: [debug] unable to decode "": json: cannot unmarshal number into Go struct field ObjectMeta.metadata.namespace of type string

I am using helm version 3.8.2. Not sure what is wrong.

@HarshManvar I have tried without qutoes, with `{{ .Values.productId | toString }}` and by passing productId as `productId: !!str 32345` but all the methods throw the same error. — Raj Sharma, Jul 18 '22 at 19:55
working fine for me even without any change, however, i am on version 3.9 — Harsh Manvar, Jul 18 '22 at 20:14
Have you tried `name: {{ .Values.productId | quote }}` (no quotes)? — Blender Fox, Jul 18 '22 at 21:05

Maybe there is no issue with the template that you have shared however i hope there is no next line

If you notice the error correctly it's on the ObjectMeta.metadata.namespace

Tried with the same version & config working fine for me
