Slice in repository `The return type is incompatible with PagingAndSortingRepository`

I have create findAll function with return type Slice then got this error: The return type is incompatible with PagingAndSortingRepository<Book,Long>.findAll(Pageable) Here is my code in repository:

import org.springframework.data.domain.Slice;

@SuppressWarnings("unused")
@Repository
public interface BookRepository extends JpaRepository<Book, Long>, JpaSpecificationExecutor<Book> {
    Slice<Book> findAll(Pageable pageable);
}

What did I do wrong here?

    That method is already available in the JpaRepository and returns a Page you >cannot redifine it with another return type and you don't actually need it >because it is already there.
