Autopatch not working when a prefix is present in the path

[froz42]

When a prefix is present in the path, the autopatch feature does not work as expected.
A 404 error occurs when a PATCH request is sent to the server.

Minimal Reproductible Example

func main() {
    router := chi.NewRouter()
    router.Route("/api", apiMux())
    err = http.ListenAndServe(fmt.Sprintf(":%d", 8080), router)
}

// apiMux returns a function that initializes the API routes
func apiMux() func(chi.Router) {
        return func(router chi.Router) {
            humaConfig := huma.DefaultConfig("API", "dev")
            humaConfig = openapi.WithAuthSchemes(humaConfig)
            humaConfig = openapi.WithOverviewDoc(humaConfig)
            humaConfig = openapi.WithServers(humaConfig, config)
            api := humachi.New(router, humaConfig)
            huma.Register(api, huma.Operation{
                Method:      "GET",
                Path:        "/ressources/{id}",
            }, getRessourceByID)
            huma.Register(api, huma.Operation{
                Method:      "PUT",
                Path:        "/ressources/{id}",
            }, updateRessourceByID)
            autopatch.AutoPatch(api)
    }
}

Technical details

The probleme is here:

huma/autopatch/autopatch.go

Line 185 in 7c5c0d3

origReq, err := http.NewRequest(http.MethodGet, ctx.URL().Path, nil)

Since ctx.URL().Path give the path with the prefix, for example /api/ressources/1, the /api prefix stay in the path given for the request, and the router does not find the route:

huma/autopatch/autopatch.go

Line 214 in 7c5c0d3

adapter.ServeHTTP(origWriter, origReq)
