Does JPA criteria api have a problem with JOIN and IN?

Question

This is a JPA Query question. I have successfully used "LEFT JOIN" and "IN:" in EntityManager.CreateQuery in separate situations, but when i combine the two e.g.

SELECT a.id 
FROM TableA a 
  LEFT JOIN TableB b on a.myAField = b.id and b.myBField in :Ids 
  LEFT JOIN TableC c on b.myBOtherField = c.id

where Ids is List<Long> it starts giving me this error "The left parenthesis is missing from the IN expression."

The sql works fine when pasted directly into postGres pgAdmin explicitly writing out the parameters. Have I made a mistake with the syntax here or is this a jpa limitation and i need an alternative?

        List<Long> myBFieldTypes = new ArrayList<>();
        myBFieldTypes.add(5L);
        myBFieldTypes.add(10L);

        try {
            List<Long> resultArray = em.createQuery("SELECT a.id FROM TableA a LEFT JOIN TableB b on a.myAField = b.id and b.myBField in :Ids LEFT JOIN TableC c on b.myBOtherField = c.id")
                    .setParameter("Ids", myBFieldTypes)
                    .getResultList();
            return resultArray;
        } catch (Exception ex) {
            throw ex;
        } finally {
            em.close();
        }
