Removing default HomePage bricks leptos

[Kiwifuit]

I tried removing the <Route path="" view=HomePage/> line and the whole function block for HomePage and I get this thread panic when I run cargo leptos watch

thread 'main' panicked at /home/misery/.cargo/registry/src/index.crates.io-6f17d22bba15001f/leptos_reactive-0.6.14/src/context.rs:316:9:

Why does it do this?

Reading between the lines, you have started with the Actix started and removed the only route, so it runs the 404 during route generation on the initial server setup. During route generation, no ResponseOptions are provided because there is no HTTP response, so the expect_context() in the NotFound page fails.

You can avoid the panic pretty straightforwardly with

        if let Some(resp) = use_context::<leptos_actix::ResponseOptions>() {
            resp.set_status(actix_web::http::StatusCode::NOT_FOUND);
        }

(this is defined in user code)

There's no reason you'd ever encounter this other than deleting all possible routes.
