I have a monorepo with ./frontend and ./backend. I managed to get the ./backend working however am struggling with the frontend.

I tried using Caddy, and have a Caddyfile and nixpacks.toml I took from https://github.com/brody192/vite-react-template using an older commit. That did not work, so I tried using the Railpack builder and I still get the application failed to respond. However, i see no errors in the build logs and it works fine locally.

npm run build builds the files.

locally running caddy run --config Caddyfile --adapter caddyfile opens a server on 3001 as well.
