Dialogflow CX Forms using custom payload

[jangaganesh]

I made this form using custom payload rich contents, I had pasted the JSON code below, here in that JSON code, for {type: input}, it is not showing the form, just for {type: info}, it is showing the static data to represent, the user on the other end was not able to enter the data in the forms. So, could anyone suggest how to solve this issue. 

{
  "richContent": [
    [
      {
        "type": "description",
        "text": [
          "Fill out the form below"
        ],
        "title": "Please enter your details"
      },
      {
        "type": "info",
        "actionLink": "input",
        "subtitle": "Please enter your name",
        "key": "name",
        "inputType": "text",
        "title": "Name"
      },
      {
        "title": "Phone Number",
        "subtitle": "Please enter your phone number",
        "inputType": "tel",
        "key": "phone_number",
        "actionLink": "input",
        "type": "info"
      },
      {
        "title": "Email",
        "actionLink": "input",
        "subtitle": "Please enter your email",
        "type": "info",
        "inputType": "email",
        "key": "email"
      },
      {
        "event": {
          "languageCode": "en",
          "name": "submitForm"
        },
        "type": "button",
        "text": "Submit"
      }
    ]
  ]
}
