[Python] Marketplace scraper suddenly stopped, they updated the hidden json?

Since yesterday, I encountered an issue where my facebook marketplace scraper ceased to fetch data, I'm currently using scrapy due to his features, am I doing any mistakes?

from scrapy import Spider
import logging
from json import loads


class Facebook(Spider):
name = 'facebook'
start_urls = ["https://www.facebook.com/marketplace/112047398814697/search?query=funko&sortBy=creation_time_descend&radius=500"]

def parse(self, response):

flex_selector = response.xpath('//*[@id="facebook"]/body/script/text()')

ads = []

for script in flex_selector.getall():
try:
ads = loads(script)
ads = ads['require'][0][3][0]['__bbox']['require'][0][3][1]['__bbox']['result']['data']['marketplace_search']['feed_units']['edges']
break
except:
pass
# if(len(ads) == 0):

for item in ads:
try:
title = adJson['node']['listing']['marketplace_listing_title']
from pdb import set_trace; set_trace()


To run the code below, runs: scrapy runspider main.py

I'm currently using py 3.12.2 and scrapy 2.11.2
