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>
    <html>
      <head>
        <title>ITS Alerts</title>

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

        <!-- Bootstrap CSS -->
        <link
          rel="stylesheet"
