on clock of Action.Submit button redirect to lambda function url

Your problem can be with the way the URL is set in the data object, the Action.Submit button does not directly handle HTTP redirects; instead, it can send data to a handler (like a bot, a service, or a webhook) to process.

Your Action.Submit can pass the email and other data to the bot or handler, and then the bot can call the Lambda function URL.

Another thing, if your bot or service receives the data, it can then initiate an HTTP request to call the Lambda function URL with the data.

// Example handler for the Adaptive Card submission
const axios = require('axios');

app.post('/handle-adaptive-card', (req, res) => {
  const { email, redirectUrl } = req.body.data;

  // Now make an HTTP request to the Lambda function URL
  axios.post(redirectUrl, {
    email: email
  })
  .then(response => {
    res.status(200).send("Redirect successful");
  })
  .catch(error => {
    console.error("Error redirecting:", error);
    res.status(500).send("Failed to redirect to Lambda function");
