Hi,  
When I’m execute my tests on my local machine in ChromeHeadless (latest version) mode: all steps is pass successfully.  
But when trying execute tests in docker(official katalon studio image), some steps with robot is failed. In logs as you can see this steps marked as “NOT\_RUN”. What’s wrong? Why some steps can have status “NOT\_RUN”?

**Part of script:**

WebUI.click(findTestObject(‘TestDomainPage/Video/vast\_playbutton’))  
WebUI.takeScreenshot()  
Robot robot = new Robot()  
robot.delay(1000)  
robot.keyPress(KeyEvent.VK\_TAB)  
robot.keyRelease(KeyEvent.VK\_TAB)  
robot.keyPress(KeyEvent.VK\_ENTER)  
robot.keyRelease(KeyEvent.VK\_ENTER)  
WebUI.takeScreenshot()  
WebUI.switchToWindowIndex(1)  
WebUI.waitForElementPresent(findTestObject(‘TestDomainPage/Zaglushka/zaglushka\_title’), 5)

Hi @a.polovinkin,

To understand why the Robot keywords didn’t run, we recommend you see the console log or try catch the robot steps:

```auto
try {
Robot robot = new Robot()
robot.delay(1000)
robot.keyPress(KeyEvent.VK_TAB)
robot.keyRelease(KeyEvent.VK_TAB)
robot.keyPress(KeyEvent.VK_ENTER)
robot.keyRelease(KeyEvent.VK_ENTER)
} catch (Exception e) {
println e
}

```

You might see **AWTException** here because the docker VM is a headless environment. the To use Robot or Java AWT, you need to setup: [Display configuration](https://github.com/katalon-studio/docker-images#display-configuration) for your docker image.
