Teams

Application Operating System

Windows

Schema Version

Problem Description

I have the below adaptive card and it doesnt render the code correctly? When not using Adaptive Cards, teams is able to process this and render everything inside code block as code block.

Expected Outcome

Render the code block as code block

Actual Outcome

Code block is being rendered as regular text

Card JSON

{
    "type": "AdaptiveCard",
    "body": [
        {
            "type": "TextBlock",
            "text": "Sure! Here's an example of code to add two numbers in Python:\n\n\nnum1 = 5\nnum2 = 10\n\nsum = num1 + num2\n\nprint(\"The sum of\", num1, \"and\", num2, \"is:\", sum)\n\n\nThis code declares two variables `num1` and `num2` with values 5 and 10 respectively. It then adds the two numbers together and stores the result in the variable `sum`. Finally, it prints the sum to the console.",
            "wrap": true
        }
    ],
    "msteams": {

}

Repro Steps

No response

Start by loading the supplied Adaptive Card JSON in Teams with schema 1.5 and compare its TextBlock rendering with the expected code-block formatting. Done means the embedded Python snippet renders as a code block rather than regular text, with the behavior verified in Teams.
