HQL, PostgreSQL : Not in clause not working, syntax error at )

Question

I am working on a Spring-MVC application, and we use Hibernate as the ORM tool. Currently, I am trying to search with a NOT in clause in Hibernate and providing a List<Integer> to it. I am getting the following error :

Error log :

org.postgresql.util.PSQLException: ERROR: syntax error at or near ")"

HQL query :

 @Override
    public List<GroupNotes> searchForTextInGroup(long groupId, String text, List<Integer> canvasNotAllowedList) {
        Session session = this.sessionFactory.getCurrentSession();
        Query query = session.createQuery("from GroupNotes as gn where gn.groupId=:groupId and gn.canvasId not in (:canvasIdList) and gn.tags like :tag");
        query.setParameter("groupId", groupId);
        query.setParameter("tag", "%" + text + "%");
        query.setParameterList("canvasIdList",canvasNotAllowedList);
        return query.list();
    }

Any ideas what we are doing wrong? Thank you.

UPDATE

Debug output with query :

Answer 1

query.setParameterList("canvasIdList",canvasNotAllowedList);

Maybe canvasNotAllowedList is empty.
