Is it possible to show more than five buttons in an Amazon Lex-v2 response display?

Here is the sessionState object I am working with:

{
"sessionAttributes": {},
"dialogAction": {
  "type": "ElicitSlot",
  "slotToElicit": "flowName"
},
"intent": {
  "name": "WelcomeIntent",
  "confirmationState": "None",
  "slots": {
    "flowName": null
  },
  "state": "Fulfilled"
}

This is the messages array being used:

[
{
  "contentType": "ImageResponseCard",
  "content": "Some content",
  "imageResponseCard": {
    "title": "Choose option",
    "subtitle": "options are",
    "buttons": [
      {
        "text": "option1",
        "value": "option1"
      },
      {
        "text": "option2",
        "value": "option2"
      },
      {
        "text": "option3",
        "value": "option3"
      },
      {
        "text": "option4",
        "value": "option4"
      },
      {
        "text": "option5",
        "value": "option5"
      },
      {
        "text": "option6",
        "value": "option6"
      },
      {
        "text": "option7",
        "value": "option7"
      }
    ]
  }
}

I am encountering an issue where Lex is not accepting more than 5 buttons in a response. The error message states that buttons should be between the 0 and 5 index range. Is there any workaround to display more than 5 buttons in a Lex response?

Answer №2

My strategy involved selectively prompting various cards following a specific slot. For example, I asked users to select a risk level (High, Medium, Low) and based on their choice, presented a corresponding prompt for a High, Med, or low slot card. It was just a creative workaround.

Answer №3

By default, the system restricts responses to a maximum of 5 size, but with some adjustments in the response logic, it is possible to allow more than 5 size.

For reference and detailed steps, you can check out this link - https://github.com/aws-solutions/qnabot-on-aws/blob/main/lambda/fulfillment/lib/middleware/lex.js#L299:L315

I have successfully implemented this by using the provided code snippet and it has worked efficiently for me. The only drawback is that it does not display the list on the LEX console, but it functions well on the integrated website UI.
