title: Bot framework-Adaptive card-Unable to get data
body: <p>I'm new to bot framework and learning. Here I'm looking for a solution I'm facing in Adaptive card that I using for my chatbot. I learn that we can design that adaptive card as per our need using adaptivecards.io/designer where we get the card as json code.</p>
  <p>so here is my json code for adaptive card</p>
  <pre><code>     {
   &quot;type&quot;: &quot;AdaptiveCard&quot;,
   &quot;$schema&quot;: 
   &quot;http://adaptivecards.io/schemas/adaptivecard.json&quot;,
   &quot;version&quot;: &quot;1.2&quot;,
   &quot;msTeams&quot;: {
   &quot;width&quot;: &quot;full&quot;
   },
   &quot;body&quot;: [
   {
    &quot;type&quot;: &quot;TextBlock&quot;,
    &quot;text&quot;: &quot;Adaptive Card Example&quot;,
    &quot;wrap&quot;: true,
    &quot;size&quot;: &quot;large&quot;,
    &quot;weight&quot;: &quot;bolder&quot;,
    &quot;id&quot;: &quot;title&quot;
   },
   {
    &quot;type&quot;: &quot;Input.Text&quot;,
    &quot;placeholder&quot;: &quot;Provide your thoughts&quot;,
    &quot;separator&quot;: true,
    &quot;isMultiline&quot;: true,
    &quot;id&quot;: &quot;thoughts&quot;
   },
   {
    &quot;type&quot;: &quot;ActionSet&quot;,
    &quot;separator&quot;: true,
    &quot;actions&quot;: [
      {
        &quot;type&quot;: &quot;Action.Submit&quot;,
        &quot;title&quot;: &quot;Submit&quot;,
        &quot;style&quot;: &quot;positive&quot;,
        &quot;id&quot;: &quot;submit&quot;
      }
    ]
   }
   ]
  }
  </code></pre>
