使用城市名称马尔默时，Aramex API返回运费错误

Question

一个项目已将Aramex API集成到系统中以收取运费。 除了一些琐碎的情况，该API正常运行。例如，

如果我将城市用作马尔默，将国家/地区用作瑞典，则会得到运费。

但是当我使用城市作为马尔默，使用国家作为瑞典时，我收到一条消息 Aramex错误-无法获取费率。

这是运费的代码：-

private static function set_shipping_rate_params($shipping_rate_request, $addresses) {
        $country_code = Country::find($addresses['shipping_address']['country'])->country_code;

        if($country_code == self::$AccountCountryCode) {
            self::$ProductType = 'CDS';
            self::$ProductGroup = 'DOM';
        }

        return array(
            'Transaction'           => array(
                'Reference1'            => $shipping_rate_request->id
            ),

            'OriginAddress'         => array(
                'City'                  => self::$OriginCity,
                'CountryCode'           => self::$AccountCountryCode
            ),

            'DestinationAddress'    => array(
                'City'                  => $addresses['shipping_address']['city'],
                'PostCode'              => $addresses['shipping_address']['postal'],
                'CountryCode'           => $country_code
            ),
            'ShipmentDetails'       => array(
                'PaymentType'            => self::$PaymentType,
                'ProductGroup'           => self::$ProductGroup,
                'ProductType'            => self::$ProductType,
                'ActualWeight'           => array( 'Value' => $shipping_rate_request->weight, 'Unit' => 'KG'),
                'NumberOfPieces'         => $shipping_rate_request->quantity,
                'Dimensions'    => array(
                    "Length"             => $shipping_rate_request->length,
                    'Width'              => $shipping_rate_request->width,
                    "Height"             => $shipping_rate_request->height,
                    "Unit"               => 'CM')
            )
        );
    }

    private static function get_shipping_rate($params) {

        $soapClient = new SoapClient(base_path("public/aramex/aramex-rates-calculator-wsdl.wsdl"), array('trace' => 1));

        $results = $soapClient->CalculateRate($params);

        if(isset($results->TotalAmount) && isset($results->TotalAmount->Value)) {
            return $results;
        } else {
            return 0;
        }
    }

我该如何解决？
