Adaptive Card errors in MS Teams "We're sorry, this card couldn't be displayed".

[suclarkeuk]

I have a very simple Adaptive card posting to Teams on Planner Task completion.  It was working before I went on holiday and then the owner asked for a very simple change.

I made the change (re-created the card in the adaptive card designer but really only removed one line of text) and now when I test the flow it doesn't work.

Flow says it has succeeded and the Output in there looks ok but in the Teams channel I get this:

There isn't really much for me to go on for troubleshooting here.  Any ideas?

Ok I solved it but gonna leave this here in case it helps anyone else out.

Some point in the last 2 weeks the version of the Adaptive card designer I've been using (https://adaptivecards.io/designer/) changed from ver 1.2 to 1.3.  That seems to have caused the problem.  

When I amended the JSON to be ver 1.2 and re-tested the card can through fine.

I'm having the same problem, v1.3 doesn't work at all. 

I specifically need the data validation function in v1.3, what is the real fix? 

I'm just trying a single date field, very simple. 

{​​​​​

    "type": "AdaptiveCard",

    "$schema": "http://adaptivecards.io/schemas/adaptive-card.json",

    "version": "1.3",

    "body": [

        {​​​​​

            "type": "Input.Date",

            "id": "startDate",

            "value": "2020-01-01",

            "min": "2000-01-01",

            "max": "2099-01-01",

            "errorMessage": "Start date is invalid"

        }​​​​​

    ]

}​​​​​

Teams displays this 

Its saying something like Teams might not support 1.3 in the designer?

Hi, did you resolve the issue? I'm receiving the same issue and also I have v1.3. I'm not sure where the issue could be.

Thank you,

Jan

I'm also having this issue when using v1.3

[ThatGuy365]

No, we gave up, decided to try adaptive cards next year or maybe never?

Did you guys got any solution?

I just had the exact same issue as above, the current version is 1.5 on the Adaptive Card designer. I have repeated errors until i read this post then changes my code to say 1.4, STUPIDLY, this worked 100%!!!

Just change the JSON version to 1.4 from 1.5 and it works fine... Another Microsoft "Feature" found - The gift that keeps on giving...

[pauldj]

Change the JSON Version to 1.4 this works for me.

thank you @pauldj ! this has worked for me too (no idea why tho :D)

[pauldj]

I put this down to a 'microsoft' feature... commonly known as error... 😀

I posted a process in a different thread that is working for me.

Would adding headers help?

"headers": [
{
"name": "Authorization",
"value": ""
},
{
"name": "Content-Type",
"value": "application/json"
}
]

I don't get this error message my card wasn't resplaying at all earlier and it was resolved by adding headers

It also helped me to delete conversations with Power Automate on teams, after running the flow once again adaptive cards displayed correctly.

Changing to 1.4 worked for me also (Desktop Microsoft Teams). But the card now causes the Teams mobile app (iPhone) to crash when the user opens the message. 😞

[MS_AU]

Thank you. Yes, just change the version to 1.4 and it works !

I am just amazed that Microsoft doesn't update their new tool to work with another tool that it was inteded for...
