Error while parsing an XML stream: 'BOM / charset detection failed' when deep create

Hi,

I am trying to create with deep structure. When I send the request with create() method of odatamodel I get Error while parsing an XML stream: 'BOM / charset detection failed' error. Here is the full error text:

1. <errorxmlns="http://schemas.microsoft.com/ado/2007/08/dataservices/metadata">
   1. <code>CX_SXML_PARSE_ERROR/001560AA0E081DEB8CA398D5EBFB9406</code>
   2. <messagexml:lang="tr">Error while parsing an XML stream: 'BOM / charset detection failed'.</message>

Here is my SAPUI5 code:

onDefaultHataSavePress : function(oEvent) {  var errorFlag = false;  var dhChild = [];  var oDHLstItems = this.getView().byId("dhLst").getItems();  var oController = this;  jQuery.each(oDHLstItems, function(i, item) {  var oDefId = item.getBindingContext().getProperty("Zzhatano");  var oContent = item.getContent()[0].getContent();  var oRContent = oContent[1].getItems();  var oFindValue = oRContent[1].getValue();  if (oFindValue.length > 5) {  var tmpMessage = oController.getView().getModel("i18n")  .getResourceBundle().getText("findValLonger");  MessageToast.show(tmpMessage, {  width : "25em"  });  errorFlag = true;  return false;  }  var oRBG = oRContent[0];  var selectedRBtn = oRBG.getSelectedIndex();  if (selectedRBtn == -1) {  var tmpMessage = oController.getView().getModel("i18n")  .getResourceBundle().getText("selectAll");  MessageToast.show(tmpMessage, {  width : "25em"  });  errorFlag = true;  return false;  }  var oRes = "OK";  if (selectedRBtn === 1)  oRes = "NOK";  else if (selectedRBtn === 2)  oRes = "NA";  dhChild.push({  Kltadm : oController.dHKaliteAdm,  Aufnr : oController.dHIsEmri,  Dhhata : oDefId,  Dhsonuc : oRes,  Bulnndgr : oFindValue  });  });  if (errorFlag)  return;  var dhHeader = {  Kltadm : this.dHKaliteAdm,  Aufnr : this.dHIsEmri  }  dhHeader.DhItem = dhChild;  var oModel = oController.getView().getModel();  oModel.setHeaders({  "Content-Type" : "application/json"  });  oModel.create("/DhHeaderSet", dhHeader, null, function() {  var tmpMessage = oController.getView().getModel("i18n")  .getResourceBundle().getText("workOrderAdded");  MessageToast.show(tmpMessage, {  width : "25em"  });  oController.getView().byId("isEmriListesiTbl").getBinding(  "items").refresh(true);  }, function(oError) {  var tmpMessage = oController.getView().getModel("i18n")  .getResourceBundle().getText("errorMsg");  MessageToast.show(tmpMessage, {  width : "25em"  });  });
