.repeater controller in jquery

Question

My code was correct however the file doesn't diplay in the ui.

<div id="sec-feature-modules" class="accordion my-5">
</div>

$("#sec-feature-modules").repeater({
  endpoint: "/content/files/features.json",
  mappingFunction: (features) => features.modules,
  messageNoResult:
    "Sorry, there are no modules available at this time. Please check back later.",
  cssClassNoResult: "empty",
});
