Missing route / 404 causes "Connection closed." error with dev server

[rmarscher]

npm create waku@latest
cd waku-project
npm run dev
open http://localhost:3000/asdf

It hits the root error boundary (which we are discussing removing in #1131) and displays "Connection closed."

If you then

npm run build
npm run start
open http://localhost:8080/asdf

you will see 404 Not Found from our default Hono notFound handler.

That is the expected behavior.

I can look into this while I work on #1131 unless you already know why the dev server behaves differently. Thanks!

I'll look into it.

Done! #1136
