Why does the page return 404 if it is present as an infoblock element in 1C-Bitrix?

Question

1C-Bitrix

Created an infoblock type - Vacancies. Created an infoblock - Vacancies, created 3 elements there. everything seems to be great. They are displayed by the module on the page where it is needed. But when going to the vacancy itself (the element of the infoblock itself), it gives the 404th error. I am attaching screenshots. Maybe I forgot to include something?
Many thanks in advance to all contributors who helped resolve this issue.
