Problem Description

Adaptive cards not taking any action on Action.Submit and no input is passed on to the Power Automate flow after clicking the button.

Upon clicking either of the buttons, the following message is posted and no action is taken on the clicked buttons.

The above image is where the flow is waiting for the input and no input is returned even after clicking the buttons.

Expected Outcome

The buttons should be actionable and should execute the intended action.

Actual Outcome

Clicking on the button has no action.

Card JSON

  "type": "AdaptiveCard",
  "$schema": "http://adaptivecards.io/schemas/adaptive-card.json",
  "version": "1.3",
  "body": [
    {
      "type": "Input.Text",
      "id": "name",
      "label": "Please enter your name:",
      "isRequired": true,
      "errorMessage": "Name is required"
    }
  ],
  "actions": [
    {

    },
    {
      "type": "Action.Submit",
      "title": "Submit"
    }
  ]
}

Repro Steps

No response

Start by reproducing the issue in Microsoft Teams with the supplied Adaptive Card JSON and inspect how Action.Submit handles associatedInputs and the Power Automate flow. Done means both buttons are actionable and the expected input reaches the flow; the issue provides no repository file or test entry point to begin from.
