The following code does not work in the template of some custom component

$arSelect = Array("ID", "NAME", "DETAIL_PAGE_URL");
$arFilter = Array("IBLOCK_ID"=>43,  "ACTIVE"=>"Y", "SECTION_ID"=>1384);
$res = CIBlockElement::GetList(Array(), $arFilter, false, Array("nPageSize"=>50), $arSelect);
while($ob = $res->GetNextElement())
{
  $arFields = $ob->GetFields();
  print_r($arFields);
}

Moreover, the section exists and there are elements in it. Generally does not fulfill the request. Dropped cache.
