    firebase-messaging-sw.js is service worker JavaScript file.

    So you should not load JavaScript file using <script src="firebase-messaging-sw.js"></script>.

    Remove <script src="firebase-messaging-sw.js"></script> and try the following code.

        <script>
      if ('serviceWorker' in navigator) {
        window.addEventListener('load', () => {
          navigator.serviceWorker.register('/firebase-messaging-sw.js');
        });
      }
    </script>

    See https://developers.google./web/fundamentals/primers/service-workers/#register_a_service_worker
