Stuck in certificate selection

[Ramonrune]

Hi!

I'am using selenium base to bypass one site. It works really well on my PC and on EC2/Virtual box. I'am creating a docker container for it, but when i run the code inside a container, it stucks in certificate selection part.

Here is a simple code:

pkcs12_file='file.pfx'
password="password"
install_certificate(pkcs12_file, password)

args ="--lang=pt-BR,"    
args += ' --verbose,'    
args += f"--load-extension={os.path.join(os.getcwd(), 'captcha_extension')}"
chromium_arg = '--auto-select-certificate-for-urls={"pattern":"*","filter":{}}' + args
driver = Driver(
    uc=True,
    headless=True,
    browser="chrome",
    chromium_arg=chromium_arg
)

driver.get("")
wait.until(EC.presence_of_element_located((By.CLASS_NAME, "sign-in")))
driver.find_element(By.CLASS_NAME, "sign-in").click()
driver.find_element(By.ID, "login").click() # Code stops here
print("Passed")

Here is my dockerfile:

FROM debian:bullseye-slim

# Install Chrome
RUN wget --no-verbose -O /tmp/chrome.deb https://dl.google.com/linux/chrome/deb/pool/main/g/google-chrome-stable/google-chrome-stable_${CHROME_VERSION}-1_amd64.deb \
  && apt-get install -y /tmp/chrome.deb \
  && rm /tmp/chrome.deb

# Update the package repository and install necessary packages
RUN apt-get update && apt-get install -y \
    python3 \
    python3-pip

RUN apt-get install libnss3-tools -y

RUN mkdir -p $HOME/.pki/nssdb

RUN mkdir -p  $HOME/etc/opt/chrome/policies/managed
COPY policies.json  $HOME/etc/opt/chrome/policies/managed/policies.json
RUN pip install requests

COPY entrypoint.sh /tmp/entrypoint.sh

COPY requirements.txt /tmp/

RUN pip install --requirement /tmp/requirements.txt
COPY main.py /main.py

ENTRYPOINT ["/bin/bash", "/tmp/entrypoint.sh"]

In the final part, there is a captcha too, which i use another solution to break (not on the above code). Notice that policies.json is the following: { "AutoSelectCertificateForUrls": ["{\"pattern\":\"*\",\"filter\":{}}"] }

Any ideas about what is could be? Code runs easily on my pc, but in container it is stucked.

I see several things that can be improved:

---

• There's already an extension_dir arg for the Driver() manager: https://github.com/seleniumbase/SeleniumBase/blob/2036a7b9b4218daffb8a7106481134c6529ae3cc/seleniumbase/plugins/driver_manager.py#L110

(Use existing args rather than passing to chromium_arg when you can.)

---

• Regular extensions don't work with regular Chrome headless mode. SeleniumBase has a headless2 option to trigger the newer headless mode: https://github.com/seleniumbase/SeleniumBase/blob/2036a7b9b4218daffb8a7106481134c6529ae3cc/seleniumbase/plugins/driver_manager.py#L68

(There's a Stack Overflow post about the newer headless mode here: https://stackoverflow.com/a/73840130/7058266 - which is triggered by headless2 in SeleniumBase.)

---

• In the case that the newer headless2 mode still has issues, use a virtual display. Since you're using the Driver() manager, you may need to use https://github.com/mdmintz/sbVirtualDisplay for that. If you were using the SB() manager instead, it comes with an xvfb option for that: https://github.com/seleniumbase/SeleniumBase/blob/2036a7b9b4218daffb8a7106481134c6529ae3cc/seleniumbase/plugins/sb_manager.py#L83

(The Driver() manager doesn't have xvfb as a direct arg.)

---

• The driver in SeleniumBase adds more methods than found in the original Selenium driver instance: https://github.com/seleniumbase/SeleniumBase/issues/2200#issue-1952880367

You shouldn't have to use EC.presence_of_element_located or any of the WebDriverWait syntax at all.

Use the built-in click methods for clicking:

driver.click(selector)

driver.js_click(selector)

driver.uc_click(selector)

(And especially since you're using UC Mode, you'll may need to use one of those to click without getting stuck.)

Thanks! I will test these approaches

Hi again!

Did the changes, but still not working, here is the new code:

args += " --shm-size=2g,"
args += " --privileged,"
args +=  " --verbose,"

chromium_arg = '--auto-select-certificate-for-urls={"pattern":"*","filter":{}}' + args
print(chromium_arg)

display = Display(visible=0, size=(1440, 1880))
display.start()

with SB(
    uc=True,
    headless2=True,
    browser="chrome",
    chromium_arg=chromium_arg,
    extension_dir=os.path.join(os.getcwd(), 'nocaptchaai_chrome'),
    xvfb=display
) as driver:

    driver.get("https://login.esocial.gov.br/login.aspx")

    driver.click(".sign-in")

    driver.click("#login-certificate") # Stucks here

It stops in this screen. But when running on my local computer, it runs with no problem.

@mdmintz Any ideas?

[mdmintz]

Looks more like a Dockerfile config issue than a SeleniumBase one since it's working in your other environment. I don't have any more suggestions to offer other than the ones I already provided.

Hi @mdmintz , i found the problem!

If anyone has this problem, i solved it in this way:

On the last line of docker:
RUN apt-get install -y libnss3-tools wget xvfb x11vnc fluxbox
These two lines will be used for remote connection and debugging. 
RUN mkdir ~/.vnc
RUN x11vnc -storepasswd 123456 ~/.vnc/passwd  # Replace 123456 with your desired VNC password
Here is the trick
CMD ["sh", "-c", "Xvfb :0 -screen 0 1024x768x16 & fluxbox & x11vnc -forever -usepw -create & python main.py"]

Xvfb: Display server
fluxbox: Windows manager
x11vnc: remote access 

On main,py:

from sbvirtualdisplay import Display
display = Display(visible=0, size=(1440, 1880))
display.start()

with SB(uc=True,
                headless=False,
                browser="chrome",
                chromium_arg=chromium_arg,
                xvfb=display) as driver:
