It would be useful if you described the problem you are facing instead of putting a screenshot of the code that tells me nothing

Presumably you would like to timestamp the entity with the LocalDateTime.now() before inserting it into the database.
First of all, your "createTransaction" method should ingest a DTO request. The ObjectMapper component will take care of the mapping between the incoming DTO and a new Transaction entity.

In order to automate the create and update of the LocalDateTime on the entity, make all the entities, including Transaction, to inherit a BaseEntity that handles automatically the update on the "date_updated" column.
After the mapping, you save and flush on the repository, which gives you back the newly created managed entity, and you return the a DTO out of it, not the entity itself.

@MappedSuperclass
@Getter
public abstract class BaseEntity implements Serializable {

  @Serial 
  private static final long serialVersionUID = 202504040001L;

  @CreationTimestamp(source = SourceType.VM)
  @Column(name = "date_created", nullable = false, updatable = false)
  @ColumnDefault("CURRENT_TIMESTAMP")
  private LocalDateTime dateCreated;

  @CreationTimestamp(source = SourceType.VM)
  @Column(name = "date_updated", nullable = false)
  @ColumnDefault("CURRENT_TIMESTAMP")
  private LocalDateTime dateUpdated;
}
