我目前使用的SDK版本3.39.0和版本0004的的API_MKT_CONTACT服务定义来创建云计算市场一个新的联系人用下面的代码：

ContactOriginData contact =
        ContactOriginData.builder()
            .originOfContact(origin)
            .originTimestamp(ZonedDateTime.now())
            .externalContactID(pii.getId().toString())
            .firstName(pii.getFirstName())
            .lastName(pii.getLastName())
            .language(pii.getLanguage())
            .countryReg(pii.getRegion())
            .build();

// use low level API as a work around for https://github.com/SAP/cloud-sdk/issues/156
ODataRequestUpdate contactRequest = service
          .updateContactOriginData(contact)
          .withHeader("Sap-Cuan-RequestTimestamp", getFormattedTime(System.currentTimeMillis()))
          .withHeader("Sap-Cuan-SequenceId", "UpdatePatch")
          .withHeader("Sap-Cuan-SourceSystemType", "EXT")
          .withHeader("Sap-Cuan-SourceSystemId", "sdk-test")
          .toRequest();

String servicePath = "/sap/opu/odata/SAP/API_MKT_CONTACT_SRV;v=0004";
ODataRequestBatch requestBatch =  new ODataRequestBatch(servicePath, ODataProtocol.V2);
requestBatch.beginChangeset().addUpdate(contactRequest).endChangeset();
HttpClient httpClient = HttpClientAccessor.getHttpClient(destination);
ODataRequestResultMultipartGeneric batchResult = requestBatch.execute(httpClient);

运行它会产生以下错误：

{
  "error": {
    "code": "/IWFND/CM_MGW/096",
    "message": {
      "lang": "en",
      "value": "PATCH requests require components to be updated"
    },
    "innererror": {
      "application": {
        "component_id": "CEC-MKT-DM-IC",
        "service_namespace": "/SAP/",
        "service_id": "API_MKT_CONTACT_SRV",
        "service_version": "0004"
      },
      "transactionid": "3B63A2A6CC920630E0060492A51E7EE7",
      "timestamp": "20210310210334.4378960",
      "Error_Resolution": {
        "SAP_Transaction": "For backend administrators: use ADT feed reader \"SAP Gateway Error Log\" or run transaction /IWFND/ERROR_LOG on SAP Gateway hub system and search for entries with the timestamp above for more details",
        "SAP_Note": "See SAP Note 1797736 for error analysis (https://service.sap.com/sap/support/notes/1797736)",
        "Batch_SAP_Note": "See SAP Note 1869434 for details about working with $batch (https://service.sap.com/sap/support/notes/1869434)"
      },
      "errordetails": []
    }
  }
}

但是，如果我在 Postman 中执行类似的请求，它可以正常工作：

我应该注意，我也尝试过使用.replacingEntity()which 也不起作用并产生完全不同的错误：

Inline component is not defined or not allowed (HTTP PUT)

SDK 中是否存在我遗漏或未正确使用的内容？任何帮助，将不胜感激！

干杯!
