Ocaml version 5.5 not compiling on the codecrafters test engine

I am working on the HTTP server challenge in OCaml; however, it does not appear that version 5.4, the most recent one is supported on the test engine. My code works locally; however, it does not compile when testing citing that String.split_all is unbound.

Thank you for reporting it. I’ve updated OCaml to v5.5 for the HTTP server challenge.
