This happens because Yelp's robots.txt file disallows web crawlers from accessing the specific URLs you were trying to scrape.
Like many websites, Yelp uses robots.txt to instruct web crawlers on which parts of their website are off-limits to indexing and scraping. When a website's robots.txt file disallows a particular URL or directory, web crawlers like Scrapy typically respect those rules and do not fetch the disallowed content.
In your case, it seems that Yelp has disallowed access to the page you were attempting to scrape. You can check the robots.txt file from the following link
https://www.yelp.com/robots.txt
