}

fn main() {
    let app = App::new().service(
        web::resource("/index.html").app_data(
            // change query extractor configuration
            web::Query::<Info>::configure(|cfg| {
                cfg.error_handler(|err, req| {  // <- create custom error response
                    error::InternalError::from_response(
                        err, HttpResponse::Conflict().finish()).into()
