When i am passing _soupEntryId as externalIdPath its not updating our existing record set(not updating the previous value) using salesforce standard api, SDK version-8.3.0. 

//workOrderId is which we are reciving from //Salesforce after sync data

//for example workOrderId = "a3E030000006Rf1EAE"

if(workOrderId){
    smartstore.upsertSoupEntriesWithExternalId(
      false,
      soupName,
      [wOItem],
      "6",//this is my soup entry Id
      (wOItem) => successCallback(wOItem[0]),
      errorCallback
    );


  }else{
    smartstore.upsertSoupEntries(
      false,
      soupName,
      [wOItem],
      (wOItem) => successCallback(wOItem[0]),
      errorCallback
    );

  }
