        $extension = pathinfo($filePath, PATHINFO_EXTENSION);
        $mime = MimeType::get($extension);

It seems like $extension can also be of type array; however, parameter $extension of Utilities\Router\Utils\MimeType::get() does only seem to accept string, maybe add an additional type check?

        return $mime !== false ? $mime : 'text/plain';

The condition $mime !== false is always false.

    }
