I have used “On image appear” activity and inside the do i have used “Click image” activity. The thing is it was running fine and doesn’t throw an error, however it was showing error notification such as “one or more children have validation error or warning” when i open the code.
Even if the activities inside “On Image Appear” are commented out, ensure that the “On Image Appear” activity itself is correctly configured. Specifically, check the selector or image properties to make sure they are valid and refer to an existing UI element.
or else, you can try deleting it and recreating it from scratch. This can often resolve strange validation errors.
