i'm creating a desktop application with selenium and python.. this app gets some data from my website with selenium .. it works fine without any problems untill i tried to run chrome in headless mode .. like that:
opt = Options()
opt.add_argument("--headless")
cpanel_window = webdriver.Chrome("chromedriver.exe", options=opt)
cpanel_window.get(mywebsite)
it works fine but in the console there are werid messages appear after sometime..

the application doesn't stop but those messages are really annoying because i print the steps and reports in console so i need it clean.. is there any way to avoid or hide those messages ?
You might need to add a few additional Options to Chromedriver to bypass the warnings.
For headless mode, I also add --disable-gpu and --window-size=1920,1200 to set the proper window size for my tests -- if the browser is too small, elements will render differently. --disable-gpu is recommended by chromedriver devs here.
You may also want to add --no-sandbox and --allow-insecure-localhost to help with the HTTPS errors you are seeing.
Added by the original asker: To hide the Javascript warnings you are seeing, you can set --log-level=3
