Image inserted in incoming webhook is not working for new Teams version.

I am trying to insert an image into an incoming webhook using adaptive card and message card. But it is not displaying in the new Microsoft Teams version (23217.806.2340.1703.).

But this is working on Old Teams version 1.6.00.24078 (64-bit).

I am using below sample code to display this card.

{
    "type": "message",
    "attachments": [
        {
            "contentType": "application/vnd.microsoft.card.adaptive",
            "contentUrl": null,
            "content": {
                "$schema": "http://adaptivecards.io/schemas/adaptive-card.json",
                "type": "AdaptiveCard",
                "version": "1.5",
                "body": [
                    {
                        "type": "TextBlock",
                        "text": "For Samples and Templates, see [https://adaptivecards.io/samples](https://adaptivecards.io/samples)"
                    },
                    {
                        "type": "Image",
                        "url": "https://adaptivecards.io/content/cats/1.png"
                    }
                ]
            }
        }
    ]
}
