Returning a http request to bangle js

I'm currently working on getting my bangle js to send a post request to a webserver and then after a period of time, submit a get request to the webserver, to the retreive the result the first post would cause.

I've tried running a test script to confirm the watch is picking up the get data but I can't get it to display the output onto the screen.

Below is the test script I'm running which I believe should work. Also I've added the getabridge debud logs which (as I understand them) confirm I am at least getting the data from the 'get' request.

Is there an issue with my code approach to getting the output to return correctly, or is there something else I may have missed in the documentation that I need to be doing?

Apologies if it's something to do with the Promie resolution. Still trying to get my head around async functions.

const credentials = btoa(`${username}:${password}`);

function getPost() {
  return new Promise((resolve, reject) => {
    Bangle.http(
      serverUrl,
      {
        method: 'GET',
        headers: {
        'Authorization': `Basic ${credentials}`
      }
    }, (err, response) => {
      if (err) {
        console.error("Error received:", err);
        reject(err);
      } else {
        console.log("Response received:", response);
        resolve(response);
      }
    });
  });
}

function swipeHandler(LR, UD) {
  if (LR === -1) {

    getPost().then(response => {
      g.clearRect(0, 0, g.getWidth(), g.getHeight()); 
      g.setFont('Vector', 20);
      g.drawString(response, 10, 40); 

    }).catch(error => {
      console.error("Error handling swipe:", error);
      g.clearRect(0, 0, g.getWidth(), g.getHeight()); 
      g.setFont('Vector', 20);
      g.drawString("fail", 10, 40); 
    });

  }
}

Bangle.on('swipe', swipeHandler);
