Use something like:

```

use axum::error_handling::HandleErrorLayer;

use axum::Router;

use hmac_predicate::HmacQueryParamValidator;

use reqwest::StatusCode;

use tower::{BoxError, ServiceBuilder};

#[tokio::main]

async fn main() {

	let predicate: HmacQueryParamValidator = HmacQueryParamValidator {

		key: API_SECRET.to_string(),

	};

	let builder = ServiceBuilder::new()

		.layer(HandleErrorLayer::new(handle_error))

		.filter(predicate);

	let app = Router::new()

		.route("/", get(handler))

		.layer(builder);

}

async fn handle_error(err: BoxError) -> (StatusCode, String) {

	(

		StatusCode::INTERNAL_SERVER_ERROR,

		format!("Unhandled internal error: {}", err),

	)

}
