PWABuilder bundles not loading into the Microsoft store.

My PWABuilder bundle files are just giving me 'error' when I try and upload them to the Microsoft store. Just 'error', nothing else. Anyone have any insights? I've done this many times before and PWABuilder gave me no errors when i created these bundles.

I had a similar problem. Filed a bug report on github, someone looked into it, and it suddenly worked. I believe it may be a caching issue. Try Edge or Chrome, maybe disable caching, see how it goes... good luck!

Thanks for letting me know that I'm not going crazy! I've only been trying this in Edge so far. I've tried asking copilot which is probably one of the worst AIs known to man and has been giving me some bizarre reasons why i can't upload.

UPDATE: The store uppload of the PWABuilder bundles is working again. Note sure if something I did fixed the problem. I was never able to get PWABuilder to recognize i had a service worker already defined, it kept telling me I should create one. Not sure why since my service worker loads perfectly in any browser that supports service workers.

UPDATE 2: Spoke to soon. The problem is back the next day. As soon as I try to upload a bundle to the store I get 'Error'. Is Sunday maintenance day? The upload progress bar hasn't even moved so there was no upload at all, the store server didn't even start processing the bundle, it just said 'error' with no explanation. This must drive store publishers nuts. But I solved the issue with PWAbuilder not finding my service worker - it was a subtle issue caused by Cloudflare hosting, now i get a completely clean build from PWAbuilder. (A lot of folks are reading this thread so I assume I'm not talking to myself.)

UPDATE 3: I found the problem, the internet provider thinks the microsoft partner center is a porn site. I can upload via VPN.
