流口水未终止的收集元素错误

Question

我有从if语句到else语句的语句时：

rule "rule"
 ruleflow-group "ruleFlow"
    when
    $block : Block()
    $inst : BlockInstitution(blockInstitutionCategory!=null) from $block.getInstitution()
    $categorycode : InstitutionCategory(Constants.INSTITUTION_CATEGORY_CODE.equals(institutionCategoryCode)) from $inst.getInstitutionCategory()
    $list : BlockInstitution(Constants.validNonList not contains dealCode) from $block.getInstitution()
    then
    Service $service = new Service();
     try {
          JsonObject enquiry =
              $service.execute($block.getTransaction().getNumber()).get();
          if (enquiry.isEmpty()) {
            $block.getBusinessValidationResult().add(ValidationResult.NOT_FOUND);
            $block.getMsg().setStatusText(Constants.NOT_FOUND);
     } 
     else {
            String numberFromService = statusEnquiry.getString(Constants.NUMBER);
            String cardExpiryFromService =
                enquiry.getString(Constants.EXPIRY_DATE);
            String paymentRequestorIdentifier =
                enquiry.getString(Constants.IDENTIFIER);
            String paymentExpiryDate = enquiry.getString(Constants.EXPIRY_DATE);
            String statusText = enquiry.getString(Constants.STATUS_TEXT);
            String providerIdentifier =
                enquiry.getString(Constants.PROVIDER_IDENTIFIER);
             if (Objects.nonNull(paymentExpiryDate)) {
                  paymentExpiryDate =
                      EncryptionUtilFactory.getInstance().decryptData(paymentExpiryDate);
                  if (paymentExpiryDate.length() == 4) {
                    paymentExpiryDate =
                        paymentExpiryDate.substring(2, 4) + paymentExpiryDate.substring(0, 2);
                  }
                  paymentExpiryDate =
                      EncryptionUtilFactory.getInstance().encryptData(paymentExpiryDate);
                }
              if (Objects.nonNull(cardExpiryFromService)) {
               cardExpiryFromService =
                   EncryptionUtilFactory.getInstance().decryptData(cardExpiryFromService);
               if (cardExpiryFromService.length() == 4) {
                 cardExpiryFromService =
                     cardExpiryFromService.substring(2, 4) + cardExpiryFromService.substring(0, 2);
               }
               cardExpiryFromService =
                   EncryptionUtilFactory.getInstance().encryptData(cardExpiryFromService);
             }
            
            
            $block.getTransaction().setServiceNumber(numberFromService);
            $block.getTransaction().setServiceAccountExpirationDate(cardExpiryFromService);
            $block.getTransaction().setPaymentExpiryDate(paymentExpiryDate);
            $block
                .getTransaction()
                .setFlag(Constants.ID_SET.contains(providerIdentifier));

            
            $block.getTransaction().setProviderIdentifier(providerIdentifier);
            String text = $block.getTransaction().getPrimaryAccountNumber();
            $block.getTransaction().setText(text);
            $block.getTransaction().setStatusText(statusText);
            $block
                .getTransaction()
                .setPaymentRequestorIdentifier(paymentRequestorIdentifier);

            if (!Constants.STATUS.equals(statusText)) {
              switch (statusText) {
                case Constants.INACTIVE_STATUS:
                  $block.getBusinessValidationResult().add(ValidationResult.INACTIVE);
                  break;
                case Constants.CANCELLED_STATUS:
                  $block.getBusinessValidationResult().add(ValidationResult.CANCELLED);
                  break;
                case Constants.SUSPENDED_STATUS:
                  $block.getBusinessValidationResult().add(ValidationResult.SUSPENDED);
                  break;
                default:
                  break;
              }
            }
          }
        } catch (Exception ex) {
          $block.getBusinessValidationResult().add(ValidationResult.CALL_FAILED);
          $block.getTransaction().setStatusText(Constants.NOT_FOUND);
        }

end

错误：

[Error: unterminated collection element]
[Near : {... _FOUND);          } else {            String numberFr ....}]

由于代码从if块到其他块，因此会给我一个错误：“未终止的集合元素”。

您看到的任何指示出了什么问题的东西。我在互联网上找不到讨论此错误的任何内容。我发现了“未终止的字符串元素”，但没有收集元素。
