Scrapy scraping the wrong page?

Question

Python

In general, to consolidate knowledge of scrapy, I decided to make a parser for steam things from cs go. I ran into a problem that the first page is parsed, and when the second link is served, the data from the first link arrives again, after looking at the logs, I realized that the link of the form https://steamcommunity.com/market/search?appid=730... becomes https: //steamcommunity.com/market/search?appid=730 - this is the first page. It turns out that he parses the same page twice, then gives an error that this is a repeated parsing and cuts down the spider.

Answer 1

everything after # is not transferred to the server
such sites are parsed wrong,
see Console what is there and where and from where
