Comment 1 Carl George 🤠 2025-08-24 04:38:23 UTC 
This was fixed upstream in caddy 2.10.1, which updated the bundled github.com/go-chi/chi/v5 to 5.2.2.

https://github.com/caddyserver/caddy/commit/3bd413546bf8f7b5e19fcb2104a21600c55cc146

That version also bumps the minimum required golang version to 1.25, which is currently only available in Fedora 43+.
