AdaptiveCard sent via webhook to Teams when searching in channel displays "Card - access it on https://go.sykpe.com/cards.unsupported."

Question

I have a teams channel with a webhook configured and I am sending a basic AdaptiveCard

{  
   "type":"message",  
   "attachments":[  
      {  
         "contentType":"application/vnd.microsoft.card.adaptive",  
         "contentUrl":"null",  
         "content":{  
            "$schema":"https://adaptivecards.io/schemas/adaptive-card.json",  
            "type":"AdaptiveCard",  
            "version":"1.2",  
            "body":[  
                {  
                "type": "TextBlock",  
                "text": "For Samples and Templates, see [https://adaptivecards.io/samples](https://adaptivecards.io/samples)"  
                }  
            ]  
         }  
      }  
   ]  
}  

The card displays fine within the channel itself but when searching the channel - CMD/CTRL + F - all results displayed are just returning "Card - access it on https://go.sykpe.com/cards.unsupported."

Has anyone else experienced this issue? Any ideas on what the issue may be?

Microsoft Teams Version 1.5.00.12661

Answer 1

We are able to repro the issue. We have used the provided JSON to send adaptive card to Teams channel using Incoming webhook.
The card got posted successfully in channel, but on searching its returning "Card - access it on https://go.sykpe.com/cards.unsupported."

We are checking it with engineering team if its expected or not. We will inform you once we get any Update. Thanks!

I had this same issue. I was able to fix it by providing a valid subject in the json payload. Change your json to look like this:

{  
   "type":"message",
   "subject":"Your Subject",
   "attachments":[  
      {  
         "contentType":"application/vnd.microsoft.card.adaptive",  
         "contentUrl":"null",  
         "content":{  
            "$schema":"https://adaptivecards.io/schemas/adaptive-card.json",  
            "type":"AdaptiveCard",  
            "version":"1.2",  
            "body":[  
                {  
                "type": "TextBlock",  
                "text": "For Samples and Templates, see [https://adaptivecards.io/samples](https://adaptivecards.io/samples)"  
                }  
            ]  
         }  
      }  
   ]  
}
