I'm using EUI's Next.js starter and am trying to make this into a PWA -- here is the repo. I haven't done anything crazy different from the EUI starter. Upon running npm run build; npm run start I get
workbox-030153e1.js:1 Uncaught (in promise) bad-precaching-response: bad-precaching-response :: [{"url":"http://localhost:3000/public/themes/eui_theme_amsterdam_dark.e7b2d22ec11f782218ad.min.css","status":404}

Which I think results the PWA audit in Lighthouse to fail:

I've tried excluding the themes/ folder from the caching step but this hasn't worked.

Any ideas?

Thanks in advanced!
