Are you referring to the routes set in wrangler.toml? I tried defining the /ip route there, still got 404.

Once your build code runs, wrangler takes any changes you made and writes them using the Cloudflare API. Once that's done, it should be reflected inside the dashboard on dash.cloudflare.com, and you could see what was actually set up.
