Microsoft Bot Framework Composer - Send Slack Block Kit

Question

Using Microsoft Bot Framework Composer, I would like to send a response to a Slack channel using Block Kit. I've tried creating a response with a JSON attachment, but the bot returns:

The bot encountered an error or bug. To continue to run this bot, please fix the bot source code.

# SendActivity_pTmt7x()
[Activity
    Attachments = ${json(SendActivity_pTmt7x_attachment_R1WWzr())}
]

# SendActivity_pTmt7x_attachment_R1WWzr()

- ${SlackMessage()}

# SlackMessage()

- # slackmessage
- ```

{

"type": "Attachment",
"name": "blocks",
  "content": [
    {
      "type": "section",
      "text": {
        "type": "mrkdwn",
        "text": "This is a sample Slack Block Kit"
      }
    },
    {
      "type": "divider"
    }
  ]
}

Is it possible to construct a Response that can render Block Kit UI properly in Slack?

Answer 1

The Slack Adaptor was not properly configured. I disabled the Slack channel in Azure Bot configuration and setup the Slack Adaptor in Composer.

# slackmessage()`enter code here`
