Why is error 500 issued when calling bitrix:catalog.item?

Question

1C-Bitrix

I am changing the templates of the "Catalogue" component. When called

$APPLICATION->IncludeComponent(
  'bitrix:catalog.item',
  '',
  array(
    'RESULT' => array(
      'ITEM' => $item,
      'BIG_LABEL' => 'N',
      'BIG_DISCOUNT_PERCENT' => 'N',
      'BIG_BUTTONS' => 'N',
      'SCALABLE' => 'N'
    ),
    'PARAMS' => array_merge($generalParams,
      array('SKU_PROPS' => $arResult['SKU_PROPS'][$item['IBLOCK_ID']]))
  ),
  $component,
  array('HIDE_ICONS' => 'Y')
);

an error 500 is issued (if you comment out this call, the page is displayed normally).
Next, I will give examples of the values ​​of variables (calls about 20).

See server error logs (error_log). Detailed messages about the causes of errors are logged there, incl. server (which the 500th is), and there will also be a full traceback where you had an error.
