Help with my script Please

Question

     This is a script that I am using to batch flatten and rotate(if needed) files. This script is working intermittently and I can't seem to get a handle on why I keep getting the error message:
     - Could not save as "" because the file could not be found.
     Line: 66
     executeAction( idsave, desc64, DialogModes.NO );
Please if anyone could help me that would be great.  It is getting rather annoying that it works sometimes and other times it does not. Thanks in advance.

You can turn off some of the dialogs with: app.displayDialogs = DialogModes.NO;
#target photoshop
if (app.documents.length > 0) {
//Turn display dialogs off
app.displayDialogs = DialogModes.NO;
//=============Find Current Documents path================//
var CurrentPath = activeDocument.path;
//=============Establish current documents destination===============//
var folder1 = Folder(CurrentPath + '/' + 'Flats');
//=============Check if it exist, if not create it.============//
if(!folder1.exists) folder1.create();
//=============Establish current documents file name=========//
//Current filename without the extension
var CurrentFileName = app.activeDocument.name.replace(/\.[^\.]+$/, '');
//=============Modify current file name================//
var modifiedFileName = CurrentFileName +"Flat.psd";
//=============Establish save path====================//
var saveFileCurrentPath = new File(folder1 + '/' + modifiedFileName);
//=============Flatten document ====================//
activeDocument.flatten();
//=============Rotate  document if in 'Landscape'====================//
var myDocument = app.activeDocument;
if (myDocument.width > myDocument.height) myDocument.rotateCanvas(90);
//============Save File=======================//
psdSaveOptions = new PhotoshopSaveOptions();
activeDocument.saveAs(saveFileCurrentPath, psdSaveOptions, true, Extension.LOWERCASE);
//Close Document
app.activeDocument.close(SaveOptions.DONOTSAVECHANGES);
