Headless Chrome WebDriverException "...page crash from unknown error"

🐛 Bug Report

Created a simple “Login” test on Yandex email website. After I login successfully any command to the driver will throw the WebDriverException, any further command will throw an exception stating the sessionId no longer exists (probably driver is closing/crashing) after the WebDriverException. This happens when executing my test on chrome headless! Works fine on regular chrome and on firefox/headless-firefox.

Expected behavior

Expecting the driver to keep responding to commands.

Test script or set of commands reproducing this issue

public static void main(String[] args) {

        WebDriverManager.chromedriver().setup();

        // Start Selenium
        StandaloneConfiguration configuration = new StandaloneConfiguration();
        SeleniumServer server = new SeleniumServer(configuration);
        server.boot();

        ChromeOptions options = new ChromeOptions();
        options.setHeadless(true);

        ChromeDriver driver = new ChromeDriver(options);
        driver.manage().timeouts().implicitlyWait(15, TimeUnit.SECONDS);
        try {
            // Do some actions with the driver...
            driver.navigate().to("https://mail.yandex.com");
            driver.findElementByXPath("//div[4]/a[. = 'Log in']").click();
            WebElement login = driver.findElementByXPath("//button[. = 'Log in']");
            login.click();
            TimeUnit.SECONDS.sleep(2);
            driver.findElementByCssSelector("#passp-field-login").sendKeys("YOUR_USER_NAME");
            login.click();
            TimeUnit.SECONDS.sleep(2);
            WebElement password = driver.findElementByCssSelector("#passp-field-passwd");
            password.sendKeys("YOUR_PASSWORD");
            WebElement login2 = driver.findElementByXPath("//*[@id=\"root\"]/div/div/div[2]/div/div/div[2]/div[3]/div/div/div/form/div[3]/button");
            login2.click();
            // AFTER THIS LINE - on chrome headless any command to the driver will reveal the bug.
            password.sendKeys("zaq123edc");
        } catch (Throwable e) {
            e.printStackTrace();
        } finally {
            driver.quit();
        }
        server.stop();
        System.exit(0);
    }

I don’t really understand what you are trying to achieve, the element won’t be present since the app will move to a different page. If it is about the precise error message, why do you need that? Are you parsing the error message for some purpose?

In the end, if it is about the headless behaviour, then please submit Chrome/ChromeDriver issues to the Chromium team, either at https://bugs.chromium.org/p/chromium or https://bugs.chromium.org/p/chromedriver. Additionally, we cannot have the same env you have to reproduce the issue, but it all points out it is not Selenium related.

If you think this is Selenium related, please provide a concise reproducible test case, that includes the page required to execute the scenario (a sample page or a public site that works in the same way for everyone).

I am pretty sure myself it is a chromedriver related issue and I already submitted a bug report to them as well but I thought you guys at Selenium might be able to give me more insight on the issue.
