Как получить SalesTaxItem из netsuite с использованием инструментария PHP

Question

Я хочу получить все SalesItemTax, но не получаю успешного ответа.

require 'samples/config.php';

use NetSuite\Classes\SearchColumnStringField;
use NetSuite\Classes\CustomerSearchBasic;
use NetSuite\Classes\SalesTaxItemSearchRowBasic;
use NetSuite\Classes\SearchRequest;
use NetSuite\Classes\SearchMoreWithIdRequest;


$service->setSearchPreferences(false, 10);

$emailSearchField = new SearchStringField();
$emailSearchField->operator = "startsWith";
$emailSearchField->searchValue = "";

$search = new SalesTaxItemSearchBasic();
$search->description = $emailSearchField;

$request = new SearchRequest();
$request->searchRecord = $search;

$searchResponse = $service->search($request);

ошибка: SearchRecord is an abstract type and cannot be instantiated

Я также пытался получить его другим методом, но не сработал.

use NetSuite\Classes\getSelectValue;
use NetSuite\Classes\RecordType;
use NetSuite\Classes\getSelectValueRequest;
use NetSuite\Classes\GetSelectValueFieldDescription;
$svr = new getSelectValueRequest();
$svr->fieldDescription = new GetSelectValueFieldDescription();
$svr->pageIndex = 1;
$priceFields = array(
'recordType'  => RecordType::cashSale,
'sublist'    => 'itemList',
'field'    => 'taxCode',
'filterByValueList'    => array(
    'filterBy'    => array(
        array(
        'field'    => 'item',
        'sublist'    => 'itemList',
        'internalId'        => '3748',
    )
        )
)
);
setFields($svr->fieldDescription, $priceFields);
$gsv = $service->getSelectValue($svr);
echo "<pre>";
print_r((array)$gsv);

ошибка: Results are incomplete. You must provide a value for the field subsidiary.

use NetSuite\Classes\SearchRequest;
use NetSuite\Classes\SalesTaxItemSearch;
use NetSuite\Classes\SalesTaxItemSearchBasic;
use NetSuite\Classes\SearchMultiSelectField;
use NetSuite\Classes\SearchEnumMultiSelectField;
use NetSuite\Classes\TaxTypeSearchBasic;
use NetSuite\Classes\setSearchPreferences;
use NetSuite\Classes\RecordRef;
//contains some login credential info

$service->setSearchPreferences(false, 20);
$search = new SalesTaxItemSearch();
//$salesItem = new SalesTaxItemSearchBasic();


//We are searching sales Order record


$SearchEnumMultiSelectField   = new SearchEnumMultiSelectField();
$SearchEnumMultiSelectField->searchValue='_unitedStates';  
$SearchEnumMultiSelectField->operator='anyOf';  

$TaxTypeSearchBasic = new TaxTypeSearchBasic();
$TaxTypeSearchBasic->country = $SearchEnumMultiSelectField;


$search->taxTypeJoin = $TaxTypeSearchBasic;



$request = new SearchRequest();

$request->searchRecord = $search;

//print_r($searchRecord);

$searchResponse = $service->search($request);

print_r($searchResponse);
if (!$searchResponse->searchResult->status->isSuccess) {
    var_dump($searchResponse->searchResult->status->statusDetail);
    echo "SEARCH ERROR\n";
} else {
    $result = $searchResponse->searchResult;
    $count = $result->totalRecords;
    $records = $result->recordList;

    foreach($records->record as $record){
        var_dump($record->tranId);
    }
    echo "\n";
    echo $count . " records were found.\n";
}

Это метод, который я получил через документ https://www.netsuite.com/help/helpcenter/en_US/srbrowser/Browser2017_2/schema/search/salestaxitemsearch.html?mode=package

Пожалуйста, дайте мне знать правильный способ получения налоговых кодов учетной записи NetSuite.
