How to successfully deploy a worker so a custom maintenance page appears if the website goes down?
Or even just a generic page ... what I have now is pretty basic, so it doesn't really matter

How to successfully deploy a worker so a custom maintenance page appears if the website goes down?
Is it possible there was something in the original code I had that would display this page correctly?

This doesn't return any errors now. However, if I preview the worker, the bare bones page doesn't appear(it says nothing is here yet)

I'm using this
export default {
fetch(req) {
const res = await fetch(req);
if (res.status >= 500) {
return new Response(maintenancePageHtml);
}
return res;
}
}
const maintenancePageHtml =
<!DOCTYPE html>
<html lang="en" style="">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Under Maintenance</title>

It was a maintenance code page I found doing a search for this; I'm not exactly the world's greatest developer so this is a bit of an unknown for me. Is there a generic template to use in this instance?
