scrapy-playwright runs but get empty json file

Question

when I crawl this site. empty json file is created. I am trying to follow along in a Udemy course and have asked about this there but have not received a reply. I have checked my code but don't see anything obvious. I was initially doing this in on PC in windows 11 but found info in scrapy-playwrght documentation that says that it doesn't work in windows and recommended Linux. I switched over to a MacBook with Ventura and get only 1 error as opposed to many on PC, but still getting empty json file. I don't know what to check. I have shown below: 1.my code 2 the end of terminal output 3. lines from my settings.py

scrapy crawl gdp -O gdp.json
