"Name cannot be blank" error when creating entity despite providing name in request body in Spring Boot

I'm working on a Spring Boot application where I need to create a Data Center using a REST API. However, I keep encountering an error stating "Name cannot be blank" even though I am providing the name field in the request body.

@Slf4j@RestController@RequiredArgsConstructor@RequestMapping(AdminConstants.API_V1_DATA_CENTER_ROOT_URL)public class DataCenterRestApi {  /**   * Create data center. if user is not admin, it will be rejected.   *   * @param dataCenterDto data center dto   * @return if the operation is success   */  @Loggable  @PreAuthorize(AUTHORIZE +" and hasRole('ADMIN')")  @PostMapping  public ResponseEntity<OperationStatus> createDataCenter(@RequestBody DataCenterDto dataCenterDto) {    // Log incoming data    Logger.getLogger(DataCenterRestApi.class.getName())        .info("Creating data center: " + dataCenterDto);    if (Objects.isNull(dataCenterDto.getName())) {      throw new IllegalArgumentException("Name cannot be blank");    }    dataCenterService.createDataCenter(dataCenterDto);    return ResponseEntity.ok(OperationStatus.SUCCESS);  }}

And here is my DataCenterDto class:

@Data@EqualsAndHashCode(onlyExplicitlyIncluded = true, callSuper = true)public class DataCenterDto extends BaseDto implements Serializable {    @Serial    private static final long serialVersionUID = -6342630857637389028L;    @EqualsAndHashCode.Include    private String publicId;    @EqualsAndHashCode.Include    @NotBlank(message = DataCenterConstants.BLANK_NAME)    private String name;    @Email(message = DataCenterConstants.INVALID_EMAIL)    private String email;    private String phone;    // Address-related fields    private String country;    private String city;    private String district;    private String address;    private String postalCode;    // Other details    private String description;    private String ownerCompany;    // Location-related fields    @DecimalMin(value = DataCenterConstants.LATITUDE_MIN, message = DataCenterConstants.LATITUDE_RANGE)    @DecimalMax(value = DataCenterConstants.LATITUDE_MAX, message = DataCenterConstants.LATITUDE_RANGE)    private BigDecimal latitude;    @DecimalMin(value = DataCenterConstants.LONGITUDE_MIN, message = DataCenterConstants.LONGITUDE_RANGE)    @DecimalMax(value = DataCenterConstants.LONGITUDE_MAX, message = DataCenterConstants.LONGITUDE_RANGE)    private BigDecimal longitude;    // Activation status    private boolean enabled;}

I am sending the following curl request:

curl -X 'POST' \'http://localhost:8080/api/v1/datacenter' \  -H 'accept: application/hal+json' \  -H 'Authorization: Bearer YOUR_TOKEN_HERE' \  -H 'Content-Type: application/json' \  -d '{"id": 0,"version": 0,"createdAt": "2024-12-19T06:25:54.376Z","createdBy": "string","updatedAt": "2024-12-19T06:25:54.376Z","updatedBy": "string","publicId": "string","name": "Test Data Center","email": "test@gmail.com","phone": "12345678901","country": "Turkey","city": "Istanbul","district": "Besiktas","address": "Test Address","postalCode": "34020","description": "Test Description","ownerCompany": "Test Company","latitude": 90,"longitude": 180,"enabled": true}'

Despite providing the name field, I receive the following error:

Name cannot be blank

I don't have data in the database. What could be causing this issue and how can I resolve it?

Any help or suggestions on resolving this issue would be greatly appreciated.
