upload function not working

Hi All,

We are trying to upload a file in feeds side panel. But for some reason its not working.

I looked at threads and tried both ways by converting the body to asString() and asArrayBuffer(). I am still getting error "$.request.entities[0] is undefined".

How to handle POST request in an xsjs file?

My code is as follows:

onFileUploadClick: function(event, data) {

        this.oFileUploadButton = event.oSource;

        this.oFileUploader = data[0];

        var oDescriptionInput = data[1];

        var oTitleInput = data[2];

        var fileName = this.oFileUploader.getValue(); 

        var description = oDescriptionInput.getLiveValue();   

        var title = oTitleInput.getLiveValue();

        if (this.getCurrentGroupID() === null) {

            this.showErrorMessage("Please choose a valid group.");

            return;

        }

        //on upload start:

        this.addBusy(this.feedView.oUploadFileContainer);

        this.oFileUploadButton.setEnabled(false);

        //this.oFileUploader.setEnabled(false); FILE UPLOADER STOPS WORKING IF DISABLED

        this.oFileUploader._bUploading = true;

        var url = "/sap/sop/sopfnd/services/collaboration/CollaborationServices.xsjs" +

                      "?objName=CollaborationFeed" +

                      "&action=handleFileUpload" +

                      "&fileName=" + fileName +

                      "&description=" + description +

                      "&groupID=" + this.getCurrentGroupID();

         var self = this;

         var file = jQuery.sap.domById("feedEntryFileUploader-fu").files[0];

         var reader = new FileReader();

         reader.readAsBinaryString(file);

         reader.onload = function(event) {

             var contents = event.target.result;

            // var contents = event.target.result.asArrayBuffer();

             console.log(contents);

             $.ajax({

                 type: "POST",

                 url: url,

                 cache: false,

                 data: contents,

                 contentType: false,

                 processData: false,

                 //headers: {"slug": fileName},

                 success: self.onFileUploadComplete,

                 error: self.onFileUploadError,

                 context: self

             }).always(function(response) {

                 self.oFileUploadButton.setEnabled(true);

                 self.oFileUploader.setEnabled(true);

             });

         };

         var formEle = jQuery.sap.domById("feedEntryFileUploader"); 

         var form = $(formEle).find("form")[0] ; 

         var fd = new FormData(form);  

        console.log("onFileUploadClick: " + url);

        this.oFileUploader.setUploadUrl(url);

        this.oFileUploader.upload();

    }

Any help would be much appreciated.

Thanks & Regards
