Issue Description

I am using HeroCard with Button type ImBack. When user click that button in telegram, it doesn't give any response or any message to my bot. In Facebook or emulator the behaviour is ok.

After that, i got an error in my channel:

Code Example

`

      public async Task TestResponse(ConnectorClient connector, Activity activity, ConversationBot conv)
       {
        Activity replyToConversation = activity.CreateReply();
        replyToConversation.Attachments = new List<Attachment>();

        List<CardAction> cardButtons = new List<CardAction>();
        cardButtons.Add(new CardAction()
        {
            Value = $"https://jsonformatter.org/",
            Type = ActionTypes.OpenUrl,
            Title = "Open Link"
        });
        cardButtons.Add(new CardAction()
        {
            Value = "Im back",
            Type = ActionTypes.ImBack,
            Title = "Im Back"
        });

        HeroCard plCard = new HeroCard()
        {
            Title = "Title",
            Subtitle = "SubTitle",
            Buttons = cardButtons,
        };

        Attachment plAttachment = plCard.ToAttachment();
        replyToConversation.Attachments.Add(plAttachment);
        await connector.Conversations.ReplyToActivityAsync(replyToConversation);
         }

I am able to reproduce at least part of this. When clicking an ImBack button the text does not display. However, the message is still being sent to my bot, are you seeing this as well?

Confirming this is a bug, but am not entirely sure if it is on our end or telegram's end yet.

Hi Jason, in my case, the message is not sent to me. I am trying to capture the whole activity to see if there any message coming from Telegram, but my controller is not getting any message.

Here my controller code

    [Authorize(Roles = "Bot")]
    [HttpPost]
    public async Task<OkResult> Post([FromBody] Activity activity)
    {
        BotBusiness bot = new BotBusiness();
        ConversationBot conversation = bot.FindConversation(context, activity, MainEngine.UserSystemId);

        SaveActivityLog(activity, conversation);

        if (activity.Type == ActivityTypes.Message)
        {
            //MicrosoftAppCredentials.TrustServiceUrl(activity.ServiceUrl);
            var appCredentials = new MicrosoftAppCredentials(configuration);
            var connector = new ConnectorClient(new Uri(activity.ServiceUrl), appCredentials);

            // return our reply to the user
            await HandleMessage(connector, activity, conversation);
        }
        else
        {
            //HandleSystemMessage(activity);
        }
        return Ok();
    }
