The Variable X needs to represent the DRS as a Prolog term.

?- drs_to_ace(drs([A], [object(A,cat,countable, na, eq, 1)-1/2]), Y).
Y= [['There is a cat.']].

or, if you want to bind the DRS to a variable X first

?- X=drs([A], [object(A,cat,countable, na, eq, 1)-1/2]), drs_to_ace(X,Y).
X = drs([A], [object(A, cat, countable, na, eq, 1)-1/2]),
Y = [['There is a cat.']].
