It looks like the column that is associated with the empty field has a
type of date. The empty string is not a valid date. If you want a NULL
date then you need to use \N instead of an empty string.

An empty string is not a valid date.
I am guessing that you just wanted the absent value(s)
to be inserted as nulls.  If so, just add "with null
as ''" (that's two single quotes) to your "copy"
statement.
