我试图通过使用2016_1端点使用java api的自定义字段在Netsuite中查找客户

我有一个错误：

“org.xml.sax.SAXException:{urn:core_2016_1.platform.webservices.netsuite.com}SearchCustomField是抽象类型，无法实例化”

SearchCustomFieldList searchCustomFieldList = new SearchCustomFieldList();
            SearchCustomField[] searchCustomFieldsArr = new SearchCustomField[1];

            SearchStringCustomField searchStringCustomField = new SearchStringCustomField();    
            SearchCustomField customefield=new SearchCustomField() {};
            customefield.setInternalId("custentity_seq_1_hrp_client_id");       

            searchStringCustomField.setOperator(SearchStringFieldOperator.is);
            searchStringCustomField.setSearchValue(customerid);

            searchCustomFieldsArr[0] = searchStringCustomField;

            searchCustomFieldList.setCustomField(searchCustomFieldsArr);
            searchCustomFieldList.setCustomField(0, customefield);
            customerSearchBasic.setCustomFieldList(searchCustomFieldList);

            SearchResult searchResult = nsPort.search(customerSearchBasic);
