No property saveAll found for type

I recently started using ReactiveCouchbaseRepository (spring-data-couchbase - 3.0.0.M2, spring-boot-starter-parent - 2.0.0.M2) in one of our projects.

I referred to unpublished doc from here and setup the project but I am getting the following error.

Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'dummyRepository': Invocation of init method failed; nested exception is org.springframework.data.mapping.PropertyReferenceException: No property saveAll found for type Dummy!

Here is the relevant information about setting up my project.

@Maven

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>2.0.0.M2</version>
    <relativePath/> <!-- lookup parent from repository -->
</parent>

...

    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-test</artifactId>
        <scope>test</scope>
    </dependency>

    <dependency>
        <groupId>org.springframework.data</groupId>
        <artifactId>spring-data-couchbase</artifactId>
        <version>3.0.0.M2</version>
    </dependency>

@java

//Repository class
public interface DummyRepository extends ReactiveCouchbaseSortingRepository<Dummy, String> {
}

//Model class
public class Dummy {

@Id
private final String id;

@Field
private final String name;

@Field
private final String address;

...
}

//Java config class
@Configuration
@EnableReactiveCouchbaseRepositories
public class CouchbaseDatabaseConfig extends AbstractReactiveCouchbaseConfiguration {

...
}

Now, i did go through this and this but here i have no custom method written in the DummyRepository class.

Note that when I change from ReactiveCouchbaseSortingRepository to CouchbaseRepository, the things works fine.

Thanks for the help in advance.
