请告诉我 scrapy 启动代码有什么问题

Question

I tried to scrapy the content(#recent_list_box > li) data of Samsung Newsroom Mexico. But it doesn't work, can you tell me why?

https://news.samsung.com/mx

think I brought the content with javascript, but I can't read i

version: scrapy: 2.1.0 splash: 3.4.1

spider code

import scrapy
from scrapy_splash import SplashRequest
from scrapy import Request


class CrawlspiderSpider(scrapy.Spider):
    name = 'crawlspider'
    allowed_domains = ['news.samsung.com/mx']
    page = 1
    start_urls = ['https://news.samsung.com/mx']

    def start_request(self):
        for url in self.start_urls:
            yield SplashRequest(
                         url,
                         self.main_parse,
                         endpoint='render.html',
                         args = {'wait': 10}
                     )

    def parse(self, response):
        lists = response.css('#recent_list_box > li').getAll()
        for list in lists:
            yield {"list" :lists.get() }

We've included the middleware involved. setting code

BOT_NAME = 'spider'
SPIDER_MODULES = ['spider.spiders']
NEWSPIDER_MODULE = 'spider.spiders'
LOG_FILE = 'log.txt'
AJAXCRAWL_ENABLED = True
ROBOTSTXT_OBEY = False
SPLASH_URL = 'http://127.0.0.1'
DOWNLOADER_MIDDLEWARES = {
    'scrapy_splash.SplashCookiesMiddleware': 723,
    'scrapy_splash.SplashMiddleware': 725,
    'scrapy.downloadermiddlewares.httpcompression.HttpCompressionMiddleware': 810,
}
SPIDER_MIDDLEWARES = {
    'scrapy_splash.SplashDeduplicateArgsMiddleware': 100,
}
DUPEFILTER_CLASS = 'scrapy_splash.SplashAwareDupeFilter'
HTTPCACHE_STORAGE = 'scrapy_splash.SplashAwareFSCacheStorage'
SPLASH_LOG_400 = True

Below are the remaining logs in the log file. I would appreciate it if you could tell me why the log below is left and why I can't read the data I want

You have to change

lists = response.css('#recent_list_box > li').getAll()

to

lists = response.css('#recent_list_box > li').getall()
