I get
com.kms.katalon.core.exception.StepFailedException: An element could not be located on the page using the given search parameters. (WARNING: The server did not provide any stacktrace information)
Command duration or timeout: 0 milliseconds
when my application window takes a while to open
You can change the implicit wait timeout using this script:
import com.kms.katalon.core.windows.keyword.WindowsBuiltinKeywords as Windows
Windows.getDriver().manage().timeouts().implicitlyWait(15, TimeUnit.SECONDS)
