Describe the bug

I am getting an error when trying to use ArgoCD to decrypt a sealed secret for Dockerconfigjson

• I am using a helm chart to pass in the dockerconfigjson value so that it will be used to create a pullsecret and mounted into a pod.
• When I pass in the raw yaml into the templates directory it works fine. But when I pass it into the values.yaml file for interpolation I get this error from ArgoCD

ErrUnsealFailed
Failed to unseal: no key could decrypt secret (.dockerconfigjson)
12

I have confirmed the set up for sealedsecret is working fine because other sealed secrets work fine. It is just the dockerconfigjson one that does not decrypt

This is a snippet of the values.yaml file

secret: 
  # If enabled is false, then the template that uses this value will not be deployed
  sslTmplRequired:
    enabled: false
  # To test HELM ARGO CD for repo secret
  testimage_name: robot-pull-secret
  testconfigjson: *****
 
  # repo-metadata-secret.yaml
  imagePullSecrets_name: stage-alfaapi-pull-secret
  dockerconfigjson: ******

And this is the corresponding file in the templates directory it should render

apiVersion: bitnami.com/v1alpha1
kind: SealedSecret
metadata:
  creationTimestamp: null
  name: {{ .Values.secret.imagePullSecrets_name }}
  namespace: {{ .Values.namespace_name }}
spec:
  encryptedData:
    .dockerconfigjson: {{ .Values.secret.dockerconfigjson }}
  template:
    metadata:
      creationTimestamp: null
      name: {{ .Values.secret.imagePullSecrets_name }}
      namespace: {{ .Values.namespace_name }}
    type: kubernetes.io/dockerconfigjson

To Reproduce

• Create a helm chart ( or use an existing one )
• Generate a sealed secret with a dockerconfig.json ( using kubeseal )
• Use the values.yaml to pass in the encrypted value for config.Json
• Commit and push up to a repo monitored by argocd
• Sync with ArgoCD

Expected behavior
ArgoCD will Sync with no issues. The sealed secret should create the corresponding secret
