數據編織：根據一個記錄集字段的值刪除重複記錄集

我需要篩選與DSUltimateId相關的響應。以下是我在測試相同時出現的錯誤。數據編織：根據一個記錄集字段的值刪除重複記錄集

ERROR 2017-08-28 16:34:13,669 [[esb-domain].HTTPS_EIP_Listener_Configuration.worker.01] org.mule.exception.CatchMessagingExceptionStrategy: 
******************************************************************************** 
Message    : Exception while executing: 
      (ns0#DSUltimateId: $.ns01#stringValue ) when $.ns01#name == "IU_ROWID" distinctBy $ ,

Cannot coerce a :array to a :boolean 
Type     : com.mulesoft.weave.mule.exception.WeaveExecutionException

這裏是我的數據編織代碼：這裏我試圖篩選出基於對可能發生的多次「DSUltimateID」 **重複的記錄。

%dw 1.0 
%output application/xml 
%output application/xml inlineCloseOn = "empty" 
%output application/xml skipNullOn="attributes" 
%namespace ns0 http://www.example.org/IUGetMasterOrganizationRecordByIdOrName 
%namespace ns01 urn:siperian.api

ns0#CustomerMasterDataDSUltimateResponse: { 
    ns0#DSUltimate: { 
     (payload.ns01#searchQueryReturn.*ns01#record.*ns01#field map 
           { 

      (ns0#ElectronicAddressTypeCd: $.ns01#stringValue) when $.ns01#name == "EADDR_TYPE_CD" and ($.ns0#stringValue != ("" and null)), 
      (ns0#ElectronicAddressTxt: $.ns01#stringValue) when $.ns01#name == "EADDR_TXT" and $.ns0#stringValue != ("" or null), 
      (ns0#DSUltimateId: $.ns01#stringValue ) when $.ns01#name == "IU_ROWID" distinctBy $ , 
      (ns0#DSUltimateNm : $.ns01#stringValue) when $.ns01#name == "IU_NM", 
      (ns0#DSUltimateClassificationCd : $.ns01#stringValue) when $.ns01#name == "IU_CLASS_CODE", 
      (ns0#ApprovalStatusDSUltimateRequesterId : $.ns01#stringValue) when $.ns01#name == "APRV_STS_IU_RQSTR_ID", 
      (ns0#DSUltimateCreateReasonCd : $.ns01#stringValue) when $.ns01#name == "IU_CRE_RSN_CD", 
      (ns0#DSUltimateApprovalStatusCd : $.ns01#stringValue) when $.ns01#name == "IU_APRV_STS_CD", 
      (ns0#DSUltimateEffectiveStartDtm : $.ns01#dateValue) when $.ns01#name == "EFF_STRT_DTM", 
      (ns0#DSUltimateEffectiveEndDtm : $.ns01#dateValue !=null) when $.ns01#name == "EFF_END_DTM" 
     } 
      ) 
    } 
}

這裏是我的樣品輸入

我無法張貼樣本輸入的問題，因爲有些怪異和不那麼有效的錯誤，在這個網站是給我。 – Dhanjeet

您正在使用distinctBy同時映射，但它應該映射後使用。請參考answer here
