Error Handling

HTTP error statuses are responses by default. Check failed(), status(), or exact status helpers after confirming the result is a Fetch response. Catch transport/request exceptions separately. In async workflows, attach a rejection callback or call catch(); await() rethrows rejection reasons.

php

try {
    $response = fetch($url);
    if (
        $response instanceof \Fetch\Interfaces\Response &&
        $response->failed()
    ) {
        // Apply application policy to the HTTP error response.
    }
} catch (\Fetch\Exceptions\ClientException $exception) {
    // Handle the transport or client failure.
}

See the error handling guide for the distinction between HTTP statuses and thrown exceptions.
