“IsRequired”不适用于 MsTeams 中自适应卡的 Input.Text

Question

I'm trying to add required validation to check whether the comment box is empty or not. I have checked on multiple places and blogs to make it work but some how validation is not working at all in Teams. When i'm using Designer of Adaptive card it is working as expected.

Below is the JSON code i'm using in my teams bot.

{
"$schema": "http://adaptivecards.io/schemas/adaptive-card.json",
"type": "AdaptiveCard",
"version": "1.3",
"body": [
           {
        "type": "Input.Text",
        "label": "Comments",
        "style": "text",
        "isMultiline": true,
        "id": "MultiLineVal",
        "isRequired": true,
        "errorMessage": "required"
    }
],
"actions": [
    {
        "type": "Action.Submit",
        "title": "Submit"
    }
]

}

Have a look at this reference on input validation and notice that it's referrring to Adaptive Cards 1.3 and above, whereas, as explained here , Teams is currently a bit behind, supporting up to Adaptive Cards 1.2 only. The products, while related, are different and have different release cycles - hopefully 1.3 will come soon for Teams.
