Bad request - please check your parameters (#100) The parameter recipient is required

Query Parameters JSON 1:

{
  "recipient": {
    "id": "{{ $('Webhook1').item.json.body.entry[0].messaging[0].sender.id }}"
  },
  "message": {
    "text": "default response message"
  }
}

Query Parameters JSON 2:

{
  "recipient": {
    "id": "{{ $('Webhook1').item.json.body.entry[0].messaging[0].sender.id }}"
  },
  "message": {
    "text": "{{ $json.response_message }}"
  }
}

why Query Parameters JSON 1 work well but Query Parameters JSON 2 not work. (only change is “text”).
