I am new to development in teams and botkit. There is a bot that is up and running on Teams. I want to share a file generated by the bot to the user(send a file from bot to the user) on teams. I have read the Microsoft-teams document. According to which first step is to send a Message requesting permission to upload which I am able to complete successfully. Below is the code, I have used to show the card to the user to ask for permission.

    controller.hears('download', ['message_received', 'direct_message', 'direct_mention'], function (bot, message) {
        var reply = {  text:"" ,attachments: [] }
        var ticketObj = {
            "contentType": "application/vnd.microsoft.teams.card.file.consent",
            "name": "result.txt",
            "content": {
                "description": "Text recognized from image",
                "sizeInBytes": 4348,
                "acceptContext": {
                    "resultId": "1a1e318d-8496-471b-9612-720ee4b1b592"
                },
                "declineContext": {
                    "resultId": "1a1e318d-8496-471b-9612-720ee4b1b592"
                }
            }
        }
        reply.attachments.push(ticketObj)
        bot.reply(message, reply)
    })

Card shown for acceptance

According to the Microsoft-teams document, when the user will click on accept button, the bot will receive an Invoke activity with a location URL. But, when I click on the accept, nothing goes to my bot. It shows the error message: "This card action is not supported".

How to provide support for this card action?

  • Is your issue resolved or are you still looking for any help? – Prasad-MSFT Jan 20 '22 at 13:03
  • I figured out that the issue is of uploading the manifest.json. So, yes the issue is resolved – lucifer Jan 27 '22 at 05:58

Adding answer from comment section for more visibility:

Issue is resolved now. The issue was of uploading the manifest.json.

To send and receive files in the bot, set the supportsFiles property in the manifest to true. This property is described in the bots section of the Manifest reference.

The definition looks like this, "supportsFiles": true. If the bot does not enable supportsFiles, the features listed in this section do not work.
