Trouble inserting image/blob into Hana table

I am currently working on a Hana UI5 application to upload an image into a Hana table. I receive an error each time from the server for the BLOB column; however, have no issue inserting a character string.

• My method to insert into the table. **

createRecord: function(success,failure,oEntry){

          var fileLoader = sap.ui.getCore().byId("uploadDemand"); 

          var fileName = fileLoader.getValue(); 

          var oEntry = {};

          oEntry.ONE = sap.ui.getCore().byId("PNText").getValue();

          oEntry.TWO= sap.ui.getCore().byId("PText").getValue();

          oEntry.THREE = sap.ui.getCore().byId("BText").getValue();

          oEntry.IMAGE1 = fileName; 

          alert(fileName);

          sap.ui.getCore().getModel("connect").setHeaders({"content-type" : "application/json;charset=utf-8"});

          sap.ui.getCore().getModel("connect").create('/Images', oEntry, null, function(response) {

               alert("Create successful");

                    if(success){

                         success(response);

                    };

               },

               function(response) { alert("Create failed");

                    if(failure){

                         failure(response);

                    }

               });

     }
