Problems with the CRubric class, why doesn't it output anything when calling the CRubric::GetList method?

Question

in general, the essence is that this code displays all our headings, but only in the component file "component.php", and in the .parameters.php file, it does not want to do this, it just outputs emptiness
here is the code:

if(!CModule::IncludeModule("subscribe"))
{
    ShowMessage(GetMessage("IBLOCK_ERROR"));
    return false;
}
$arOrder = Array("SORT"=>"ASC", "NAME"=>"ASC");
$arFilter = Array("ACTIVE"=>"Y", "LID"=>LANG);
$rsRubric = CRubric::GetList($arOrder, $arFilter);
$arRubrics = array();
while($arRubric = $rsRubric->GetNext())
{
    $arResult["RUBRIC_LIST"][] = $arRubric;
}

print_r(123);
print_r($arResult);
die();

If your site is not multilingual and you use a standard site, then, with a high degree of probability, instead of the LANG constant, you need to use the identifier 's1'
