unable to show data in html template

[mybluedog24]

Hi,

I'm trying to customize the UI of the assessment node using the HTML template. However, I couldn't find out what variable I can use in the HTML. I tried below but nothing show up:

<script>
(function() {
  var data = {{ item | default({}) | json_encode | raw }};
  var assessmentData = {{ assessment.flatItems | default([]) | json_encode | raw }};

  console.log("item:", data);
  console.log("assessment.flatItems:", assessmentData);
})();
</script>

Any helps are appreciated!
