Can run my tests in recapitated mode but not in headless

Question

I can run any of my tests in Chrome recapitated (headfull) mode but when I try to run them in headless mode, I get the following error.

[main] INFO io.github.bonigarcia.wdm.WebDriverManager - Using chromedriver 114.0.5735.90 (resolved driver for Chrome 114)
[main] INFO io.github.bonigarcia.wdm.WebDriverManager - Exporting webdriver.chrome.driver as C:\Users\user\.cache\selenium\chromedriver\win32\114.0.5735.90\chromedriver.exe

I have added the following chrome options, tried commenting a few out and running again based on this but I still get the same response.

        boolean isHeadless = true;
        ChromeOptions chromeOptions = new ChromeOptions();
        chromeOptions.setExperimentalOption("prefs", chromePrefs);
        chromeOptions.addArguments("use-fake-ui-for-media-stream");
        chromeOptions.addArguments("--window-size=1920,1080");
        chromeOptions.addArguments("--disable-gpu");
        chromeOptions.addArguments("--remote-allow-origins=*");
        chromeOptions.addArguments("lang=en-GB");
        chromeOptions.addArguments("--headless");
        chromeOptions.addArguments("--no-sandbox");
        chromeOptions.addArguments("--disable-dev-shm-usage");
        chromeOptions.setHeadless(true);

I expected it to run in headless mode as it does in recapitated mode.

Instead of boolean isHeadless = true; and/or chromeOptions.setHeadless(true); you can use the argument --headless=new as follows:

ChromeOptions options = new ChromeOptions();
options.addArguments("--start-maximized");
options.addArguments("--headless=new");
WebDriver driver = new ChromeDriver(options);

if this helps upvote and check my answer!

first thing i notice is that you are using the installed chrome drive, i recommend using the dependencie :

<dependency>
  <groupId>io.github.bonigarcia</groupId>
  <artifactId>webdrivermanager</artifactId>
  <version>5.3.3</version>
</dependency>

it will allow you to use chrome driver and firefox and others as i think

you might wanted to use :

        option.setPageLoadStrategy(PageLoadStrategy.NONE);

get inspired from this example:

    @BeforeTest
public void setUp(){
    WebDriverManager.chromedriver().setup();
    option = new ChromeOptions();
    option.addArguments("--remote-allow-origins=*");
    option.addArguments("--disable-blink-features=AutomationControlled");
    option.setPageLoadStrategy(PageLoadStrategy.EAGER);

    driver = new ChromeDriver(option);
    driver.manage().timeouts().implicitlyWait(5, TimeUnit.SECONDS);
    WebDriverManager.chromedriver().setup();
    option = new ChromeOptions();
    option.addArguments("--remote-allow-origins=*");
    option.addArguments("--disable-blink-features=AutomationControlled");
    option.addArguments("--disable-gpu");
    option.addArguments("--disable-dev-shm-usage");
    option.addArguments("--no-sandbox");
    option.addArguments("--headless"); // Run in headless mode
}

@AydinApaydin please provide more information, tell me exactly your purpose of this operation — roudlek, Jun 20 '23 at 09:39
I was trying to set up my Driver class that would work for Jenkins as well. However, I found the problem, someone added chromeOptions.addArguments("--remote-debugging-port=9222"); in browser switch case part which caused error in output. — Aydin Apaydin, Jun 20 '23 at 22:49
