Thanks @rombert , I initially tried implementing it in the constructor, but
the tests began to fail. I believe Jackson does not allow this approach when
the constructor is marked with @JsonCreator.

If the current approach doesn’t work, I will explore other solutions. If you
have any insights on what might be causing the issue with Jackson, please let
me know.
