[FIXED] Error in web scraping response a page title

Issue

I want to be a code for analysing a bet graphics. What the error has ocurred in the log ? I took the test with other famous sites and I couldn't get a response either.

scrapy runspider av/av/spiders/av.py

Above is the error log, below is my code, a very simple code just to try to receive the test information from the page

import scrapy

class AvSpider(scrapy.Spider):
    name = 'av'
    allowed_domains = ['aviator-next.spribegaming.com']
    start_urls = ['https://aviator-next.spribegaming.com/?user=896541&token=2c5aa7d41630609ddf82e58655f7299e3106a6377b678d50740ab7aa5925afdf&lang=pt&currency=BRL&return_url=&operator=demo&jurisdiction=CW']

    def parse(self, response):
        title = response.css('title::text').extract.first()
        print(title)
        pass

I want to receive a simple title, if it works i want to be start my project.

Solution

If you want to extract the first thing that matches, use the method extract_first()

import scrapy

class AvSpider(scrapy.Spider):
    name = 'av'
    allowed_domains = ['aviator-next.spribegaming.com']
    start_urls = ['https://aviator-next.spribegaming.com/?user=896541&token=2c5aa7d41630609ddf82e58655f7299e3106a6377b678d50740ab7aa5925afdf&lang=pt&currency=BRL&return_url=&operator=demo&jurisdiction=CW']

    def parse(self, response):
        title = response.css('title::text').extract_first()
        print(title)
        pass

This is currently working here for me and printing 'Aviator' as the title.
