HTML Javascript Parse CSV URL (RSS) feed

With this script, I am able to read rss feed . However, It is not able to pull any CSV feed from the url source. If you could please critic the information presented below, and show me why it is not able to pull any information.

 <!DOCTYPE html>
        <title>ITS Alerts</title>

        <!-- Required meta tags -->
        <meta charset="utf-8" />
          content="width=device-width, initial-scale=1, shrink-to-fit=no"

        <!-- Bootstrap CSS -->

        <link rel="stylesheet" href="style.css" />

          <h1>ITS Alerts</h1>
          <div id="rss-feeds"></div>
        <script src="../dist/"></script>
        <script src=""></script>
        <script src=""></script>
        <script src=""></script>
          window.onload = function() {
            const rss = new RSS(
                limit: 15,
                tokens: {
                  showClass: (entry, tokens) => (tokens.index === 0 ? "show" : "")
                '<div class="accordion" id="accordionExample">{entries}</div>',
                entryTemplate: `<div class="card">
                  <div class="card-header" id="heading-{index}">
                    <h2 class="mb-0">
                      <button class="btn btn-link" type="button" data-toggle="collapse" data-target="#collapse-{index}" aria-expanded="true" aria-controls="collapse-{index}">
                  <div id="collapse-{index}" class="collapse {showClass}" aria-labelledby="heading-{index}" data-parent="#accordionExample">
                    <div class="card-body">

            rss.render().then(() => console.log("cool"));
