How to overcome the error Call to a member function GetProperties() on boolean (0)?

Question

1C-Bitrix

Hello!

I tried to create a product without sections with a price of 0 and made an entry in the cart template:

$Cart = Sale\Basket::loadItemsForFUser(Sale\Fuser::getId(), Bitrix\Main\Context::getCurrent()->getSite());
$item = $Cart->createItem('catalog', 666); 
        $item->setFields(array(
          'PRODUCT_PRICE_ID' => 0,
          'PRICE' => -(int)$Price,
          'CURRENCY' => 'RUB',
          'QUANTITY' => 1,
          'LID' => Bitrix\Main\Context::getCurrent()->getSite(),
          'CUSTOM_PRICE' => 'Y',
          'NAME' => 'Скидон - '.$Price,
        ));
        $Cart->save();

When adding a product, an error pops up:

[Error] 
Call to a member function GetProperties() on boolean (0)
/var/www/....php:17

With the indication of the file and the line with the code:

17 строка: $articul= CIBlockElement::GetByID($mxResult['ID'])->GetNextElement()->GetProperties();

The people, who can tell how to solve this problem? When adding a product, the cart falls and the error that is indicated above appears. But if you hover over the basket in the menu, a list of products in the basket will drop out, and there will be an added product, only without a name, but with a price.

In line

$articul= CIBlockElement::GetByID($mxResult['ID'])->GetNextElement()->GetProperties();

error, since the GetNextElement method returns false, you need to add a check

$articul = [];

$dbRes = CIBlockElement::GetByID($mxResult['ID']);
if($ob = $dbRes->GetNextElement()) {
  $articul = $ob->GetProperties();
}
