I ran into an issue where extract run from within server functions failed to extract anything. After lots of head-banging and confusion, I discovered that layers had to be added after routes. So, IOW:

            let router = axum::Router::new()
                .serve_dioxus_application(ServeConfigBuilder::new(), App)
                .layer(Extension(redis))
                .layer(Extension(s3))
                .into_make_service();

instead of:

            let router = axum::Router::new()
                .layer(Extension(redis))
                .layer(Extension(s3))
                .serve_dioxus_application(ServeConfigBuilder::new(), App)
                .into_make_service();

I recognize that this is technically documented on the Axum side, but it's a bit indirect as it needs you to recognize that .serve_dioxus_application is setting up your routes, and that layers need to be added before. Even so, if there's some way to document it on the Dioxus side, or to make the Dioxus server setup immune to this somehow, that'd have saved me a few hours of debugging.

Thanks a bunch.
