How to create an information block in Bitrix?

Question

1C-Bitrix

Cannot create a new information block using the API.

$ib = new CIBlock;
$arFields = Array(
  "ACTIVE" => 'Y',
  "NAME" => 'Кирпичи',
  "CODE" => 'catalog_bricks',
  "LIST_PAGE_URL" => '#SITE_DIR#/catalog/list.php?SECTION_ID=#SECTION_ID#',
  "DETAIL_PAGE_URL" => '#SITE_DIR#/catalog/detail.php?ID=#ELEMENT_ID#',
  "IBLOCK_TYPE_ID" => 'catalog',
  "SITE_ID" => Array("ru"),
  "SORT" => 500,
  "PICTURE" => '',
  "DESCRIPTION" => '',
  "DESCRIPTION_TYPE" => '',
  "GROUP_ID" => Array("2"=>"D", "3"=>"R"),
);
$res = $ib->Add($arFields);

The result of the code returns emptiness.

Answer 1

if (CModule::IncludeModule('iblock') {
    // some code
}

Answer 2

Output $ib->LAST_ERROR after executing your code and look at the text of the error that Bitrix gives you. Correct the code according to the error.
