OPTIONAL MATCH/UUID does not return existent node

[sapalli2989]

CREATE NODE TABLE V (id UUID, PRIMARY KEY(id));
CREATE REL TABLE E (FROM V TO V);
CREATE (v1:V {id: UUID('11111111-1111-1111-1111-111111111111')})-[:E]->(v2:V {id: UUID('22222222-2222-2222-2222-222222222222')});

v1:V should be second uuid , but nothing is returned. MATCH (v:V {id: UUID('11111111-1111-1111-1111-111111111111')})-[:E]->(v1:V) RETURN v1; works though. Also replacing UUID by INT64 works.
