Scripts are not working headless mode - no such element found exception

[razz...@gmail.com]

Hi All,

I am facing an issue while running my java selenium scripts in headless mode. When I execute on non-headless mode everything works perfectly fine without any issue. 

But when I execute the same scripts in headless mode I am getting 'no such element found exception'. 

I am facing this issue majorly when there is page transition(As per my observation), I tried using debugger but still the same issue.

Could someone help to resolve this issue?

Thanks

What scripts are you referring to? Your selenium code in python/ruby/javascript/node.js/etc.? Or did you mean execution of javascript code from the JavascriptExecutor in Selenium? Please clarify.

My selenium code is in JAVA. I am using normal selenium command like driver.element.getText(),  driver.element.click().

following code resolved my problem, 

driver.manage().window().setSize( new Dimension(1920,1080)  );

Thank you

Interesting, how did you figure it out? What was the original dimensions of the headless window? I guess headless vs head mode uses different default window sizes?

did you try to get a printscreen just before the error? so you will have shure that the page are loading properly.

do you have any proxy in your organization? if yes, did you configure the proxy on capabilities options?

Hi,

1. Make sure that the element you are trying to locate is actually present in the DOM when the script is running.

2. Make sure that the element you are trying to locate is visible and not hidden by other elements on the page. Selenium will not be able to locate hidden elements.

3. Make sure that you are using the correct locator strategy to find the element. You can try using different locator strategies, such as class name, ID, or CSS selector, to see if that helps.

4. You can try adding explicit waits to your script to allow more time for the page to load and the element to become available. You can use the WebDriverWait class to do this.

5. If the element you are trying to locate is inside an iframe, you may need to switch to the iframe before attempting to locate the element. You can use the driver.switchTo().frame() method to do this.
