Don’t worry about the “Note: This element neither has attached source nor attached Javadoc and hence no Javadoc could be found.” That just means the reference was not created by Katalon, they don’t have the source code and don’t have any documentation within KS. Anyways, you can’t do anything about it.
Your concern, for the image you attached, is the “element id=filterrecord not found”. Try to find where you have that reference and if you need to wait for something to display or such.
You can find other references to this “Note error” if you search this forum.
