Hi,

Thank you for letting us know. I will create a ticket on this. Can you please provide your device version

You haven’t showed us the source code of compareImages method; therefore we can not see anything about the exception.

If you are using KS version 7.7 or above, there is a statement, WebUI.takeElementScreenshot(filename, TestObject, FailureHandling) that you might be able to use.

example:

WebUI.takeElementScreenshot(gReportPathway + "DetailsOnWhy4.png", findTestObject('myPage/textarea_DetailsCriteria'))
