404 not working on sub routes

[peterpeterparker]

Hi, I have swizzled the NotFound component to customize my 404 but, while it works fine on root URL, it isn't used for subroutes.

For example, http://localhost:3000/unknown works as expected however http://localhost:3000/docs/unknown returns the generic 404.

Same with prod build, e.g. https://juno.build/unknown vs https://juno.build/docs/unknown. With prod build deployed I briefly see my 404 but, it seems that the JS kicks it out.

Anything I can do to fix this problem?

Hmmmm yes this looks suspicious

The client-side router seems to route the url to another page for some reason, not sure why.

Can you create a minimal repro and open a bug please?

Sure of course, there you go 👉 #9665
