org.springframework.data.mapping.PropertyReferenceException: No property count found for type Employee! in Spring Data Redis

Question

I already went through urls like Spring Data JPA - "No Property Found for Type" Exception, but it did not solved my issue yet. I'm developing Spring Boot + Spring Data Redids example. In this example, I am contineously facing the below issues. I have used QueryByExampleExecutor<Employee> as suggested in https://programtalk.com/vs/?source=spring-data-examples/jpa/query-by-example/src/test/java/example/springdata/jpa/querybyexample/UserRepositoryInheritanceIntegrationTests.java

Here is the source code for reference: https://github.com/JavaHelper/spring-redis-examples/tree/master/redis-example

EmployeeRepository.java

public interface EmployeeRepository extends CrudRepository<Employee, String>, QueryByExampleExecutor<Employee>{

}

Employee.java

@Builder
@Data
@AllArgsConstructor
@NoArgsConstructor
@RedisHash("employees")
public class Employee {
    @Id @Indexed
    private String id;
    private String firstName;
    private String lastName;
    private List<Address> addresses;

    private List<Department> departments;
}

Test class/Main Method

Example<Employee> example = Example.of(new Employee(null, "Raj", null, null, null));
long count = employeeRepository.count(example);
System.out.println("COUNT_OF_EMPLOYEE = "+count);

Any Quick pointers??
