Blazor PWA not fetching app when its cached -> cannot work offline

[Laftek]

Is there an existing issue for this?

• I have searched the existing issues

Describe the bug

I converted existing Blazor WASM app to PWA and deployed as static page to cloudflare pages. On the first visit it works fine but every other visit with app already cached I get this in console
The FetchEvent for "https://incomecalculator.pages.dev/" resulted in a network error response: a redirected response was used for a request whose redirect mode is not "follow". Promise.then (async) (anonymous) @ service-worker.js:7

Repo:
https://github.com/Laftek/IncomeCalculator

App:
https://incomecalculator.pages.dev/

My main focus is to have this app working offline. Thank you.

Expected Behavior

To work even on repeat visit and most important to work offline.

Steps To Reproduce

Deploy the PWA app to cloudflare static pages
Visit the page after app is cached

Hi. It looks like this is a question about how to use ASP.NET Core. While we do our best to look through all the issues filed here, we are not a general-purpose forum. To get a faster response we suggest posting your questions to StackOverflow using the blazor tag.

@Laftek Do you know what the source of the redirect is for the initial request?

Hi @danroth27 , thanks for reaching out. I am not sure what you mean completely but I was able to fix it thanks to one guy here on github (cannot find that issue again to give him a credit) but basically the problem is with catching so I just added few lines to service worker to give new response if its redirected.

PS:
found the guy andreimilto -> #33872 Thanks!
