I'm unable to set cookies for ChromeDriver running in headless mode

Question

When I run my selenium tests using ChromeDriver in headless mode addCookie method calls cause exception; the tests all work in normal mode

My Chrome Browser version is 75.0.3770.90 and ChromeDriver version is 75.0.3770.8. The OS is Mac OS X 10.14.5

The exception I'm getting is:

    org.openqa.selenium.UnableToSetCookieException: unable to set cookie

The code causing the problem is:

    driver.get(initialPageUrl);    
    Cookie cookie = new Cookie(cookieName, encode(cookieValue, "UTF-8"), "localhost","/", null);
    driver.manage().addCookie(cookie);

Probably you added the cookie before navigating to the site. You should first navigate to your url

driver.get("yourWebPage");

and only after this add cookies

driver.manage().addCookie(cookie);

For a better analysis of what is going wrong, if above won't help, you have to add more code of your program.

Also maybe duplicate of this.
