If the element does not appear, the activity will fail. This is unlike ElementExists in that the activity fails if the selector for the element you’re waiting for does not appear. If you want to continue anyway and not run the activity within the body of OnElementAppear, set ContinueOnError to True.

Keep in mind that in debug mode, you will still see the error and the message box will still appear, so you have to use Continue to keep the process going in debug mode.
