Batch in ODATA for PUT returns 'Error while parsing an XML stream' - 'CX_SXML_PARSE_ERROR' - SAPUI5

Hi Guys,

I'm trying to send a table from my frontend to backend via ODATA call. I'm using batch processing and the code is as below.

var sPath = "emp_tabSet(Objid='121')";
changeOperations.push(oModel.createBatchOperation(sPath,"PUT",dataT[0],null));
oModel.addBatchChangeOperations(changeOperations);
oModel.submitBatch(function(oData, oResponse, aErrorResponses){
if(aErrorResponses.length>0){
sap.m.MessageBox.alert("Error in Creating. Please try again...");
console.log(aErrorResponses);
}else{
sap.m.MessageBox.alert("Batch Successfull", {});
}
});

I have also redefined the methods /IWBEP/IF_MGW_CORE_SRV_RUNTIME~CHANGESET_BEGIN and /IWBEP/IF_MGW_CORE_SRV_RUNTIME~CHANGESET_END in the backend.

I tried executing a GET request from my gateway system and it worked fine. When I tried to execute a PUT, which is actually what I need, just see a popup that says empty response received. In the browser I have 'Error while parsing an XML stream' after all the batch submissions. I tried researching the SCN forums and found that it maybe an issue with the payload but I couldn't figure out what. Here's my payload that I got from chrome.
