Fix T92327: use default value when field is passed into data socket 

Previously, the computed value passed into the data socket could depend
on the actual field a bit. However, given that the link is marked as invalid
in the ui, the user should not depend on this behavior.
Using a default value is consistent with other cases when there are
invalid links.
