How to get the 1s Bitrix location ID knowing its character code?

Question

1C-Bitrix

The character code is taken from the multiregionality module and passed to the filter, but in the end I get an empty result...

if (Bitrix\Main\Loader::includeModule('twofingers.location'))
$location = \TwoFingers\Location\Entity\Location::buildCurrent();
$smp = $location->getPrimary();

$arElm = CSaleLocation::GetList(array(), array('CODE' => $smp), false, false, array('ID'))->Fetch();

if ($arElm)

    $resultmp = (int) $arElm['ID'];

echo $resultmp;

Answer 1

function getLocationByCode(string $locationCode){
  return \CSaleLocation::getLocationIDbyCODE($locationCode);
}
