The Following error occurred: No Handler for Data

Hi,

I was making a read function for my oDatamodel, but after running my application i get this error when i check my console in Chrome:

The following problem occurred: no handler for data -

This is the function which contains the read function. For some extra information i am using the sap.ui.model.odata.v2.ODataModel for this application.

  _downloadFile: function() {  var oModel = this.getView().getModel();  var selectedDocument = this.getView().getBindingContext().getObject();  var sRead ="/PDFSet(MyDocKey='',SCObjid='',AcadYear='',AcadPeriod='',Cokey='"+selectedDocument.Cokey+"',Cotyp='"+selectedDocument.Cotyp+"')/$value";  oModel.read(sRead, {    success: function(oData, oResponse){        console.log(".. oModel.read success: " + oData.results.length);        console.log(oData);        console.log(oResponse);     },    error: function(oError){      console.log(".. oModel.read failed");      var errorObj1 = JSON.parse(oError.responseText);        console.log(errorObj1);    }
});  }

I hope you can help me figure out what i am missing or doing wrong.

Kind Regards,

Arun
