is there a way to get data from a google apps script webapp page without running into cors issues? I run into this when I make a get request from my app (currently running on localhost) to my appscript page. I am trying to get a list of folder names and urls. Please if anyone has an answer it will be much appreciated. Been trying to get past this nightmare for days now. See the error message below and my appscript's code

function getData() {
  var folders = DriveApp.getFolders();
  var foldersArray = [];
  while (folders.hasNext()) {
  var folder = folders.next();
  foldersArray.push([folder.getName(),folder.getUrl()])
  Logger.log(foldersArray)
}
var   json = Object.assign(...foldersArray.map(([k, v]) => ({ [k]: v })));
  console.log(json);

  return json;
}


function doGet(e){   
  var content = getData();
 return ContentService
    .createTextOutput(JSON.stringify(content))
    .setMimeType(ContentService.MimeType.JAVASCRIPT);
}
