selenium error with simple driver.get() method : session deleted because of page crash from unknown-CodePudding

I'm running a python selenium script on ubuntu 18.04 using Amazon EC2.

I have a list of urls, and using selenium to loop through them and get info. Here's a very simple example of my script:

import requests
import selenium
from selenium import webdriver
from selenium import webdriver
from datetime import datetime as dt
import re
import time
from selenium.webdriver.chrome.options import Options
from selenium.common.exceptions import ElementNotVisibleException
from selenium.common.exceptions import NoSuchElementException
from selenium.common.exceptions import TimeoutException
from selenium.webdriver.support.wait import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC

from selenium.webdriver.common.by import By


# set driver options
chrome_options = Options()
chrome_options.add_argument('--no-sandbox')
chrome_options.add_argument('--window-size=1420,1080')
chrome_options.add_argument('--headless')
chrome_options.add_argument('--disable-dev-shm-usage')
chrome_options.add_argument('--disable-gpu')
chrome_options.add_argument("--disable-notifications")
chrome_options.add_argument("--remote-debugging-port=9222")
chrome_options.add_experimental_option("excludeSwitches", ["enable-automation"])
chrome_options.add_experimental_option('useAutomationExtension', False)
chrome_options.add_experimental_option("excludeSwitches", ["disable-popup-blocking"])
chrome_options.binary_location='/usr/bin/google-chrome-stable'
chrome_driver_binary = "/usr/bin/chromedriver"


events = ['https://www.bandsintown.com/e/1024970351-alukah-at-high-noon-saloon?came_from=253&utm_medium=web&utm_source=city_page&utm_campaign=event', 'https://www.bandsintown.com/e/103265416-bill-roberts-combo-at-come-back-in?came_from=253&utm_medium=web&utm_source=city_page&utm_campaign=event', 'https://www.bandsintown.com/e/1022530728-chiiild-at-the-sylvee?came_from=253&utm_medium=web&utm_source=city_page&utm_campaign=event', 'https://www.bandsintown.com/e/103243450-aimee-mann-at-stoughton-opera-house?came_from=253&utm_medium=web&utm_source=city_page&utm_campaign=event', 'https://www.bandsintown.com/e/1022530781-leon-bridges-at-the-sylvee?came_from=253&utm_medium=web&utm_source=city_page&utm_campaign=event', 'https://www.bandsintown.com/e/103338969-jonathan-coulton-at-stoughton-opera-house?came_from=253&utm_medium=web&utm_source=city_page&utm_campaign=event', 'https://www.bandsintown.com/e/1024312079-necronomicon-at-high-noon-saloon?came_from=253&utm_medium=web&utm_source=city_page&utm_campaign=event', 'https://www.bandsintown.com/e/103395650-jon.-at-jitters-coffeehouse?came_from=253&utm_medium=web&utm_source=city_page&utm_campaign=event', 'https://www.bandsintown.com/e/1024311602-the-convalescence-at-high-noon-saloon?came_from=253&utm_medium=web&utm_source=city_page&utm_campaign=event', 'https://www.bandsintown.com/e/1024691276-todd-sheaffer-at-the-bur-oak?came_from=253&utm_medium=web&utm_source=city_page&utm_campaign=event', 'https://www.bandsintown.com/e/103127087-alec-benjamin-at-the-sylvee?came_from=253&utm_medium=web&utm_source=city_page&utm_campaign=event', 'https://www.bandsintown.com/e/1024272496-sara-kays-at-the-sylvee?came_from=253&utm_medium=web&utm_source=city_page&utm_campaign=event']


for event in events:
    print("getting event")
    driver = webdriver.Chrome(executable_path=chrome_driver_binary, chrome_options=chrome_options)
    driver.get(event) #crashes!
    time.sleep(3)
    print(driver.title)
    driver.quit()

I get:

  (Session info: headless chrome=101.0.4951.41)

What I've tried:

I've tried increasing the size of my amazon EC2 instance. It's now got 16gb of memory, so I don't think that's the issue.
Tried countless tweaks to the chrome_options, including the --no-sandbox and '--disable-dev-shm-usage' options.
Tried stopping/restarting instance.
Tried pkill chrome and pkill -f "(chrome)?(--headless)" commands to the command line to make sure all chrome processes are killed. No luck.
Ensured chromedriver and google-chrome are same version. They are. (version 101.0.4951.41).
Ensured the location of chrome/chromedriver binaries are correct. google-chrome and chromedriver are both in usr/bin.
Tested it locally - it works locally. Just fails on ubuntu EC2 instance.

Please help. I'm ready to give up on selenium and just use something else. Thanks.

UPDATE:

It seems like the issue is with this particular list of urls. For example, if I change the url list to this:

events = ["https://www.facebook.com",
            "https://www.reddit.com",
            "https://www.linkedin.com",
            "https://yahoo.com",
            "https://google.com",
            "https://quora.com",
            "https://sweetwater.com",
            "https://amazon.com",
            "https://youtube.com",
            "https://github.com",
            "https://stackoverflow.com",
            "https://worpress.com",
            "https://medium.com"]

The script seems to be run more reliably and I don't get a page crash.

So, what is it about the urls in my original question that are causing the crash? Could it be those urls have too much information that's overloading selenium? If so, is there a way to load those urls more simply so they don't get bogged down with the map, popups, etc?

CodePudding user response：

There's an error in your drive instance code:

driver = webdriver.Chrome(executable_path=chrome_driver_binary, chrome_options=chrome_options)

It's supposed to be:

driver = webdriver.Chrome(executable_path=chrome_driver_binary, options=chrome_options)

The parameter for options in webdriver.Chrome is "options" not "chrome_options"

A few points:

You're supposed to create one instance of the driver and run commands under that, in your code you kept quiting and creating new instances (unless that is intentional for some reason?).
I recommend you use the package "Webdriver-Manager" rather than manually hardcoding paths.
To import selenium webdriver all you do is from selenium import webdriver. So delete the rest.

So your final code would look like:

import requests
from selenium import webdriver
from datetime import datetime as dt
import re
import time
from selenium.webdriver.chrome.options import Options
from selenium.common.exceptions import ElementNotVisibleException
from selenium.common.exceptions import NoSuchElementException

from selenium.webdriver.chrome.service import Service
from selenium.webdriver.support.wait import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
from webdriver_manager.chrome import ChromeDriverManager

chrome_options.add_argument('--disable-gpu')
chrome_options.add_argument("--disable-notifications")

chrome_options.add_experimental_option("excludeSwitches", ["enable-automation"])
chrome_options.add_experimental_option('useAutomationExtension', False)
chrome_options.add_experimental_option("excludeSwitches", ["disable-popup-blocking"])

CodePudding user response：

Seems you were pretty close to the root cause of the error...

selenium.common.exceptions.WebDriverException: Message: unknown error: session deleted because of page crash
from unknown error: cannot determine loading status
from tab crashed

...implies that the loading status cannot be determined.

Deep Dive

Seems you have taken care of all the facts mentioned in the discussion unknown error: session deleted because of page crash from unknown error: cannot determine loading status from tab crashed with ChromeDriver Selenium and you were good to go.

However, it seems after opening a couple of the initial urls, all of a sudden an url opens with:

Show notifications popup.
SIGN IN popup.

popups

The very first time these popup shows up within any of the urls, without handling them you can't perform any operation as the page isn't completely loaded which justifies your suspection that ...is there a way to load those urls more simply so they don't get bogged down with the map, popups, etc....

You can find a detailed discussion on how to handle the notification in How to allow or deny notification geo-location microphone camera pop up
