When I using the recorder, updated version of the mobile screen was not visible in device view. I got “Unable to capture objects: ExecutionException”

java.lang.NullPointerException

Was able to create a test using below “CustomKeyword”

```auto
@Keyworddef tapPickerview_mobile(){MobileElement ele1 = driver.findElementByClassName("XCUIElementTypePickerWheel")ele1.sendKeys("秋田県");}

```
