Ajax whitelist

[NiackZ]

Hello. First of all - thank you for your work!
I get the WhiteList from the server through AJAX and I get an error in the console + the drop-down list is empty. I was trying to do what you described in this topic.

Can you tell me where I got it wrong, please?

<input type="text" name="type_tags" value="">
<script src="../js/jquery-3.4.1.min.js"></script>

<link href="https://cdn.jsdelivr.net/npm/@yaireo/tagify/dist/tagify.css" rel="stylesheet" type="text/css" />
<script>
let type_input = document.querySelector('input[name="type_tags"]'),
type_tagify = new Tagify(type_input, {
    whitelist : [],
    enforceWhitelist:true,
    maxTags:1
});

type_tagify.on('input', getWL());
async function getWL(){
  type_tagify.settings.whitelist.length = 0;
  type_tagify.loading(true).dropdown.hide.call(type_tagify);
  var newWhitelist = await take_type();
  newWhitelist = JSON.parse(newWhitelist);
  console.log('newWhitelist down');
  console.log(newWhitelist);
  type_tagify.settings.whitelist.push(newWhitelist);
  type_tagify.loading(false).dropdown.show.call(type_tagify);
}
async function take_type(){
  return await $.ajax({
    type: 'POST',
    url: 'test.php',
    data: 'qq=0'
  });
}
</script>
