Getting "selenium.common.exceptions.WebDriverException: Message: disconnected: Unable to receive message from renderer" in Driver(uc=True)

I am getting "selenium.common.exceptions.WebDriverException: Message: disconnected: Unable to receive message from renderer" in Driver(uc=True)

google search suggests adding --no-sandbox and --disable-dev-shm-usage but I can see they are already added in line

I am using Python 3.10 with latest SeleniumBase and here is snippet from my code

from seleniumbase import Driver
from sbvirtualdisplay import Display
from selenium import webdriver
chrome_options = webdriver.ChromeOptions()

prefs = {"profile.managed_default_content_settings.images": 2}
chrome_options.add_experimental_option("prefs", prefs)

with Display(visible=0, size=(1440, 1880)):

    driver = Driver(
        uc=True, 
        browser='chrome',
        cap_string=chrome_options.to_capabilities()
    )
    driver.get('https://www.website.com/')

cap_string can only be used when connecting to Selenium Grids that support it:
(And UC Mode won't work on a Selenium Grid)

SeleniumBase/seleniumbase/plugins/sb_manager.py

Line 47 in 77ee514

cap_string=None, # The desired capabilities to use with a Selenium Grid.

There's already an option to block images: block_images:

SeleniumBase/seleniumbase/core/browser_launcher.py

Line 814 in 77ee514

prefs["profile.managed_default_content_settings.images"] = 2

The SB() format might help solve your issue: (https://github.com/seleniumbase/SeleniumBase/blob/master/help_docs/syntax_formats.md#sb_sf_21)
It has extra code for handling those situations.

@mdmintz sorry for confusing you.

My basic purpose was not to disable images.
It was actually to get your suggestion why the selenium.common.exceptions.WebDriverException: Message: disconnected: Unable to receive message from renderer error is happening?

[mdmintz]

That's usually related to Chrome trying to display something in a headless environment such as Linux. Maybe try something from #2426 (reply in thread) - The SB(uc=True) format may be more useful that the Driver(uc=True) format in this case.

[iamumairayub]

@mdmintz Hi, just letting you know that error still persists even after using SB(uc=True)

[mdmintz]

Try upgrading the version of Chrome on your machine. Looks like it was something that appeared for uses on Chromium 119 and Chromium 120 (Chrome and Edge), but not on newer versions: MicrosoftEdge/EdgeWebDriver#126
(This issue is not specific to SeleniumBase.)

[iamumairayub]

@mdmintz just did, but issue still persists.

@mdmintz how do set xvfb window size?

with SB( uc=True, xvfb=True, browser='chrome', ) as sb:
    pass

I used to do it with Driver like this

with Display(visible=0, size=(1600, 900))

[mdmintz]

With SB() and BaseCase, Xvfb is automatically used as needed. Default width: 1440 Default height: 1880

[iamumairayub]

@mdmintz I understand its not a Python or SB issue. But you have any suggestions for me to fix this?
I am running Google Chrome 120.0.6099.224
I saw your above linked github issue but that guy says upgrading chrome didnt solve issue MicrosoftEdge/EdgeWebDriver#126 (comment)

[iamumairayub]

One hint is that I have more instances of this script running on server, could that cause some issue with xvfb or something?

any solution to the problem? @iamumairayub
