Solutions

1. Remove @GeneratedValue from the non-identifier property of the embeddable.
2. Or restructure so the generated property is the entity identifier.

When it happens

Trigger: An identifier/value generator declaration is inconsistent with the referenced generator or the annotated element.

Common situations: @GeneratedValue pointing at a generator of the wrong kind (SEQUENCE vs TABLE), a missing named generator, too many generator annotations, or an unsupported generation strategy for @CollectionId.
