The latest version of spring-boot v3.1.0, which comes with jackson-bom to v2.15.0, introduced a buggy version of jackson-databind that breaks the deserialisation of Java Record classes. The issue has been fixed already in v2.15.1 (see release notes Jackson-Release-2.15.1).
I've added v2.15.1 as an explicit dependency version, which resolved the issue in the meantime.
