Soap/Order/getOrderListResponse

[Eayshwary]

the code written in construct of this class GetOrderListResponse.php is like
public function __construct($response)
{
$reader = new \Zend\Config\Reader\Xml();
$this->_dataResponse = $reader->fromString($response);
if ($this->isOperationSuccess($this->_dataResponse['s:Body']['GetOrderListResponse']['GetOrderListResult']))
{
$this->_orderList = new OrderList();
/**
* Global informations
/
$this->_setGlobalInformations();
/*
* Order list
*/
$this->_setOrderList();
}
}

but when fetching orders with \Sdk\Order\OrderStateEnum::ShippedBySeller this as an state

the response is this ->

Array
(
[s:Body] => Array
(
[s:Fault] => Array
(
[faultcode] => Array
(
[_] => a:DeserializationFailed
[a] => http://schemas.microsoft.com/net/2005/12/windowscommunicationfoundation/dispatcher
)

                [faultstring] => Array
                    (
                        [_] => The formatter threw an exception while trying to deserialize the message: There was an error while trying to deserialize parameter http://www.cdiscount.com:orderFilter. The InnerException message was 'Invalid enum value 'ShippedBySeller' cannot be deserialized into type 'Cdiscount.Service.Marketplace.API.External.Contract.Data.Order.OrderStateEnum'. Ensure that the necessary enum values are present and are marked with EnumMemberAttribute attribute if the type has DataContractAttribute attribute.'.  Please see InnerException for more details.
                        [lang] => fr-FR
                    )

            )

    )

)

so in construct it is not getting the DataResponse key $this->_dataResponse['s:Body']['GetOrderListResponse']

cause breakdown and fatal error on site

quick fix

/**
* GetOrderListResponse constructor.
* @param $response
*/
public function __construct($response)
{
$reader = new \Zend\Config\Reader\Xml();
$this->_dataResponse = $reader->fromString($response);
$checkExistence = $this->_dataResponse;
if (isset($this->_dataResponse['s:Body']['GetOrderListResponse']['GetOrderListResult'])) {
if ($this->isOperationSuccess($this->_dataResponse['s:Body']['GetOrderListResponse']['GetOrderListResult']))
{
$this->_orderList = new OrderList();

            /**
             * Global informations
             */
            $this->_setGlobalInformations();

            /**
             * Order list
             */
            $this->_setOrderList();
        }
    }
}

but need to see why serialisation fails and the fatal error comes in some more states like this while order fetching
