KeyError: 'driver' or 'screenshot'

[afperezp]

hey i just started to scrape with scrapy-selenium but i am always getting this same problem. My mentor suggested adding Webdriver to the path, but the problem is not fixed, any suggestions?

What's your code ?

[uselessvevo]

Same thing. Can't access response.meta['screenshot'] or 'driver' in my middleware

I'm facing the same issue. As requested by @tristanlatr above, here's my code -

`import scrapy
 from scrapy_selenium import SeleniumRequest
 from selenium import webdriver
 from shutil import which
 import requests

  class LinkedinCrawlerSpider(scrapy.Spider):
          name = 'linkedin_crawler'
          allowed_domains = ['www.linkedin.com']

    def start_requests(self):
        yield SeleniumRequest(
            url = 'https://www.linkedin.com/sales/login',
            wait_time = 5,
            callback = self.login
        )
    def login(self, response):

        print(response.request.meta['driver'].title)`

@raghavsehgal1 Did you activate the downloader middleware in the settings.py ?

[raghavsehgal1]

@tristanlatr Yes, I did. scrapy-selenium related Code snippet from settings.py -

   DOWNLOADER_MIDDLEWARES = {
                  'scrapy_selenium.SeleniumMiddleware': 800
              }

  from shutil import which

  SELENIUM_DRIVER_NAME = 'chrome'
  SELENIUM_DRIVER_EXECUTABLE_PATH = which('chromedriver')
  SELENIUM_DRIVER_ARGUMENTS=['--headless']  # '--headless' if using chrome instead of firefox

I have been trying multiple approaches but I have been unable to figure out why the issue persists. I tried to print the meta object without any keys. This is the object that was printed -

{'download_timeout': 180.0, 'download_slot': 'golden.com', 'download_latency': 0.34168577194213867}

I had a similar issue and was resolved by making sure driver arguments is set to ['--headless'] i.e. two dashes for chrome

I had the same issue, it turned out that I don't have the driver installed. (it's says in the log that the driver name and driver path is not set, so the selenium middleware is disable)

The issue solved after install the chromedriver or geckodriver.

Hope this help.

I had the same issue. I get this error when debugging, but the code seems to be working fine.

['--headless'] Hi @blackwhiteman It's still the same issue i changed as the following: SELENIUM_DRIVER_NAME = "chrome" SELENIUM_DRIVER_EXECUTABLE_PATH = '/drivers/chromedriver' SELENIUM_DRIVER_ARGUMENTS = ['--headless']
