Selenium Chrome Error: You are using an unsupported command-line flag: --ignore-certifcate-errors

Question

Okay so I am learning Web Scraping and am comfortable with Java hence I choose Jsoup, which is a web scraping library. I planned on scraping A CodeChef contest problem (which is just a coding problem), but I found difficulty scraping all the displayed content, which is not possible as most of it is dynamic source. So I used selenium to render the JavaScript and obtain simple HTML page and then feed it to JSOUP.

So I tried printing the rendered HTML page just to verify, but I get the following error when I run the code:

My Code:

    File f = new File("<Path to chromedriver.exe>");
    System.setProperty("webdriver.chrome.driver", f.getAbsolutePath());
    WebDriver driver = new ChromeDriver();
    driver.get("https://www.codechef.com/problems/FRGTNLNG");
    System.out.println(driver.getPageSource());

Error (in chrome):

You are using an unsupported command-line flag: --ignore-certifcate-errors. Stability and security will suffer

I tried the following solution from Chrome Error: You are using an unsupported command-line flag: --ignore-certifcate-errors. Stability and security will suffer, I installed the latest chromedriver but it didn't resolve my error.

I also tried adding Desired Capabilities (now deprecated) and ChromeOptions as per Pass driver ChromeOptions and DesiredCapabilities?, but the same error persists.

Thanks in advance!

The error says it all :

You are using an unsupported command-line flag: --ignore-certifcate-errors. Stability and security will suffer

As per best programming practices, use the ChromeOptions Class to open Chrome Browser being maximized, disabling the infobars and disabling the extensions as follows :

System.setProperty("webdriver.chrome.driver", "C:\\path\\to\\chromedriver.exe");
ChromeOptions options = new ChromeOptions();
options.addArguments("start-maximized");
options.addArguments("disable-infobars");
options.addArguments("--disable-extensions");
options.addArguments("--test-type");
options.addArguments("--ignore-certificate-errors");
WebDriver driver =  new ChromeDriver(options);
driver.get("https://www.google.co.in");

Additionally, perform the following steps :

Update your JDK to the most recent versions JDK 8u162
Upgrade Selenium-Java Clients to v3.10.0.
Upgrade ChromeDriver to the latest release ChromeDriver v2.35
Clean up the Project Space from your IDE.
Run CCleaner tool to wipe off all the OS system chores.
If your base Web Browser version is too old, then uninstall it through Revo Uninstaller and install a recent GA and released version of the Web Browser.
Take a System Reboot.
Execute your @Test

I tried all of above but the error still shows. Is there any specific argument for ignoring certificates? — specbug, Mar 03 '18 at 18:47
I've tried everything (except updating my browser), seems like a browser version issue to me. Anyways, I moved to HTMLUnit which worked perfectly fine for me! — specbug, Mar 05 '18 at 16:08
