spring数据中的ReactiveCouchbaseSortingRepository，用于沙发床反应式，不允许在Pageable查询中使用find参数

我有一个名为MyEntity的pojo，如下所示。当我在下面不使用Pageable的情况下运行第二个查找查询时，它会正确返回响应，但是当我使用Pageable参数运行时，则在初始化应用程序时它将抛出以下异常。

Caused by: java.lang.IllegalStateException: Method has to have one of the following return types! [interface org.springframework.data.domain.Page, interface java.util.List, interface org.springframework.data.domain.Slice]

尽管它应该按照参考文档以及适用于MongoDb的方式工作

public class MyEntity {
    @Id
    private String id;
    private Instant effectiveDateTime;
    private String createdBy;
    private Instant createdDateTime;
}

public interface EntityRepository extends ReactiveCouchbaseSortingRepository<MyEntity, String> {

Flux<MyEntity> findByEffectiveDateTimeBetween(Instant start, Instant end, Pageable pageable) ;
Flux<MyEntity> findByEffectiveDateTimeBetween(Instant start, Instant end) ;
}

进一步阅读时，似乎是spring数据共享库中的错误。因为弹簧数据中用于检查返回类型的类QueryExecutionConverters.java在其列表中不包含Flux或任何响应类型。

有人可以确认它的文档错误还是spring数据公用程序中的代码错误。

ALLOWED_PAGEABLE_TYPES.add(Slice.class);
ALLOWED_PAGEABLE_TYPES.add(Page.class);
ALLOWED_PAGEABLE_TYPES.add(List.class);

ReactiveCouchbaseSortingRepository不允许在查找查询中使用Pageable参数
