FF update won't allow any access to page

I have a public page for my web app which was loading fine for a while. All of a sudden the page is no longer showing and I am receiving this:

Exception while loading service worker: DOMException: Failed to register a ServiceWorker for scope ('https://my.flutterflow.app/example/#####) with script ('https://my.flutterflow.app/example/#####/flutter_service_worker.js?v=YVsGmeYJ1MXjoazNTURA'): The script has an unsupported MIME type ('text/html'). (anonymous) @ flutter.js:368
