Range issue in go template in vault configuration in k8s

I don't know Golang at all but need to implement Go template syntax in my kubernetes config (where hishicorp vault is configured). What I'm trying to do is to modify file in order to change its format. So source looks like this:

data: map[key1:value1]
metadata: map[created_time:2021-10-06T21:02:18.41643371Z deletion_time: destroyed:false version:1]

The Kubernetes config part with go template is used in order to format file is here:

apiVersion: apps/v1
kind: Deployment
metadata:
  name: test
spec:
  replicas: ${REPLICAS}
  selector:
    matchLabels:
      component: test
  template:
    metadata:
      labels:
        component: test
      annotations:
        vault.hashicorp.com/agent-inject: 'true'
        vault.hashicorp.com/agent-inject-status: 'update'
        vault.hashicorp.com/role: 'test'
        vault.hashicorp.com/agent-inject-secret-config: 'secret/data/test/config'
        vault.hashicorp.com/agent-inject-template-config: |
          {{- with secret "secret/data/test/config" -}}
          {{ range $k, $v := .Data.data }}
          export {{ $k }}={{ $v | quote }}
          {{ end }}
          {{- end}}
    spec:
      serviceAccountName: test
      containers:
        - name: test
          image: ${IMAGE}
          ports:
            - containerPort: 3000

But the error I'm getting is:

runtime error encountered: error="template server: (dynamic): parse: template: :2: unexpected "," in range"

EDIT:

• To deploy vault on k8s I'm using vault helm chart
