The QuerydslJpaPredicateExecutor cannot be picked up due to missing reflection configuration.

Conditional hint should be

hints.reflection().registerType(QuerydslJpaPredicateExecutor.class,
	hint -> hint.withMembers(MemberCategory.INVOKE_PUBLIC_CONSTRUCTORS, MemberCategory.INVOKE_PUBLIC_METHODS)
		.onReachableType(QuerydslPredicateExecutor.class));
