It seems like $result can also be of type array; however, parameter $string of Pronamic\WordPress\Pay\Core\Util::simplexml_load_string() does only seem to accept string, maybe add an additional type check?

			if ( is_wp_error( $xml ) ) {

It seems like $xml of type SimpleXMLElement is incompatible with the declared type WP_Error of property $error.
