Spring Data Mongo API Can't find a codec for interface java.util.List

I am using Spring-boot (2.0.8.RELEASE) and connecting MongoDB. While finding Documents using mongoTemplate, getting this exception; no issue in result.

Can't find a codec for interface java.util.List.

Collection<String> names = getNames(); 
Query query = new Query(Criteria.where("name").in(names )); 
List<Employee> employeeList = mongoTemplate.find(query, Employee.class)

@Document(collection = "employee")
@Getter
@Setter
@JsonInclude(JsonInclude.Include.NON_NULL)
@JsonIgnoreProperties(ignoreUnknown = true)
public class Employee {
    @Id
    @JsonIgnore
    private String _id;
    
    private String name;
    private List<String> deptNames;
    private List<Orgs> orgNames;
    private Data[] datas;
  

}
