If you've built objects on older versions of BP and now they have the following errors:
Row x supplies a blank expression to argument 'Attribute Identifier'
Simply click on the area you would think you write text and its actually a dropdown menu and from what I've built can see it normally matches the above value.
Also you may see another error:
Row x does not supply a value to the compulsory parameter
This is normally on the Wait which I found just reselecting the values "Check Exists" etc normally clears this error.
