Webhook Callback URL not recieving Challenge

Woops, should’ve posted that as well, I appreciate your time for responding.

 app.get('/SubscribeTwitch*',(request, response) => {
  console.log(request.query['hub.topic']);
  console.log(request.params)
  console.log(request.query)
  var challenge = request.query['hub.challenge'];
  console.log(challenge);
   response.set({
        'Access-Control-Allow-Origin': '*',
        'x-timestamp': Date.now(),
        'x-sent': true
    })

  response.status(200).send(challenge);
});

Right now I’m just trying to print out anything that comes through. I’m able to send a GET request through XMLRequest Browser with response 200. Plugging URL into browser with params works fine too.
