For what reason is the trade offers infoblock not indexed?

Question

1C-Bitrix

Good afternoon.
The site has a search implemented through search.title. In the drop-down list of this search, links to trade offers lead to a non-existent page.
I'm re-indexing the search, the links are not updated.

IB settings:
Information block page URL: #SITE_DIR#/catalog/
Section page URL: #SITE_DIR#/catalog/#SECTION_CODE_PATH#/
Detail view page URL: #SITE_DIR#/catalog/#SECTION_CODE_PATH#/#ELEMENT_ID#/
Canonical element URL : https://new.ru/catalog/#SECTIO ... EMENT_ID#/
(you must specify the protocol, server address and path on the site)
