A lot has changed between 1.2.5 and 2.3.2. I doubt that the client side is the problem, so I'd start looking at your repository REST resources and the backing data store which I assume is JPA. Perhaps the biggest change here is the jump from Hibernate 4.3 to Hibernate 5.4. If I was you, I would start your investigation there. If you'd like some further help, please follow up on Stack Overflow or Gitter, providing a minimal sample that works with 1.2 and fails with 2.3.
