You need to add or change the code to the finished code

There is a site that loads some data via json, and my code was initially parsing the html page simply, but then I noticed that the data did not match and as it turned out they were loaded via json

Site Link https://www.mechta.kz/section/smartfony/

Here is a link to the json but it's only one page visible

From here I need to take OldPrice and Price

The code itself is an application that scrapes various sites

This code collects data and uploads
