HttpPost Action fails with BadRequest

We use the https://docs.microsoft.com/en-us/microsoftteams/platform/webhooks-and-connectors/how-to/add-incoming-webhook feature to send notifications from our application backend to our internal Teams channel in some situations that require employee intervention (This is not a question about some kind of public Teams integration). I'm trying to add actionable notifications to our Teams workflow by adding an HttpPost action to our messages:

{
    "@type": "MessageCard",
    "@context": "https://schema.org/extensions",
    "summary": "Manual Verification Required",
    "themeColor": "#2196F3",
    "text": "<message content here>",
    "title": "Manual Verification Required",
    "potentialAction": [
        {
            "@type": "HttpPOST",
            "name": "Approve",
            "target": "https://our.application.host/teams/webhook",
            "body": "verification.approve"
        }
    ]
}

 

The message arrives in teams properly:

 
 

 

Upon clicking the button though, immediately the following error message appears:

:warning: Failed to send:
There was a problem submitting your changes. Try again in a minute.

After scratching my head, I opened the Teams web app and checked the console:

}

So the only valuable information returned from the server seems to be the response {"errorCode":"BadRequest"}. That's a little thin.

I tried different variations of the body property - with quotes, without, with a content type, empty - no change.

What do I have to do to get message actions working?
