UC work without headless but not work with headless option ON?

[JohnDoe15152]

Hello, I have been using undetected chromedriver for a few months with my scripts. Recently the headless mode has stopped working, while with non-headless everything works. Does anyone know why and how to fix it please? Thanks for the work and have a nice day!

@JohnDoe15152 I have the same issue, it works except when I enable the headless option.

I am experiencing the same issue.

The sample code runs:

import logging
logging.basicConfig(level=10)
import undetected_chromedriver as uc
driver = uc.Chrome()
driver.get('https://nowsecure.nl') # or any other website

But when adding headless=True to the driver as such:

import logging
logging.basicConfig(level=10)
import undetected_chromedriver as uc
driver = uc.Chrome(headless=True)
driver.get('https://nowsecure.nl') # or any other website

The following occurs:

Chromedriver is version 112.0.5615.49 to align with Chrome 112.0.5615.138.

Try setting window size explicitly for headless mode(as in, add --window-size=1920,1080 to options). "New Headless" mainlined in Chrome 110 sets default viewport for headless windows to 0x0 pixels.
