春季400個錯誤的請求錯誤

我得到這個錯誤有什麼想法會導致它嗎？我試圖發送一個DTO，它有一個擴展了抽象類的對象列表。我認爲這個問題可能適用於DTO中的列表，或者是因爲抽象類中的子類？春季400個錯誤的請求錯誤

@Autowired 
private RestClient restClient; 


@Override 
public ReceiptDto create_TicketIdentifier_For_Sale(TicketSaleDto tiDto) 
     throws ServiceException { 

    RestTemplate restTemplate = this.restClient.getRestTemplate(); 
    String url = this.restClient.createServiceUrl("/ticketIdentifier/"); 
    HttpHeaders headers = this.restClient.getHttpHeaders(); 
    //headers.add("Content-Type", MediaType.APPLICATION_FORM_URLENCODED_VALUE); 
    HttpEntity<TicketSaleDto> entity = new HttpEntity<>(tiDto, headers); 

    ReceiptDto ti = null; 
    try { 
     ParameterizedTypeReference<ReceiptDto> ref = new ParameterizedTypeReference<ReceiptDto>() {}; 
     ResponseEntity<ReceiptDto> response = restTemplate.exchange(URI.create(url), HttpMethod.POST, entity, ref); 
     ti = response.getBody(); 
     // System.out.println(ti.getEntryDto().getReceiptDto().getCustomerDto().getLastname()); 
    } catch (RestClientException e) { 
     e.getStackTrace(); 
     throw new ServiceException("Could not retrieve ticketIdentifiers: " + e.getMessage()); 
    } 
    return ti;
