Question about missing measurements in SVG files

Hello everyone,

I have a problem with the new illustrator version when using a script to convert AI files to SVG files.
Suddenly the measurement in the SVG files is missing, there is no "width" or "heigt" parameter.

Here is the script I am using:

Save as SVGs.jsx

DESCRIPTION

This sample gets files specified by the user from the 
selected folder and batch processes them and saves them 
as SVGs in the user desired destination with the same 
file name.

Based on Adobe's "Save as PDFs" sample script, intended for Illustrator CS6
 
**********************************************************/

// Main Code [Execution of script begins here]

// uncomment to suppress Illustrator warning dialogs
// app.userInteractionLevel = UserInteractionLevel.DONTDISPLAYALERTS;

var destFolder, sourceFolder, files, fileType, sourceDoc, targetFile, svgSaveOpts;

// Select the source folder.
sourceFolder = Folder.selectDialog( 'Quell-Verzeichnis mit AI-Dateien auswählen', '~' );

// If a valid folder is selected
if ( sourceFolder != null )
{
  files = new Array();
	fileType = prompt( 'Select type of Illustrator files to you want to process. Eg: *.ai', ' ' );
	
	// Get all files matching the pattern
	files = sourceFolder.getFiles( fileType );
	
	if ( files.length > 0 )
	{
		// Get the destination to save the files
		destFolder = Folder.selectDialog( 'Ziel-Verzeichnis für die SVGs auswählen.', '~' );
		for ( i = 0; i < files.length; i++ )
		{
			sourceDoc = app.open(files[i]); // returns the document object
									
			// Call function getNewName to get the name and file to save the SVG
			targetFile = getNewName();
			
			// Call function getSVGOptions get the SVGSaveOptions for the files
			svgSaveOpts = getSVGOptions( );
			
			// Save as svg
			sourceDoc.exportFile(targetFile, ExportType.SVG, svgSaveOpts );

			sourceDoc.close();
		}
		alert( 'Files are saved as SVG in ' + destFolder );
	}
	else
	{
		alert( 'No matching files found' );
	}
}


/*********************************************************

getNewName: Function to get the new file name. The primary
name is the same as the source file.

**********************************************************/

function getNewName()
{
    var ext, docName, newName, saveInFile, docName;
    var docName = sourceDoc.name;
    var ext = '.svg'; // new extension for svg file
    var newName = docName.replace(/\.[a-z]+$/, ext);

// Create a file object to save the svg

saveInFile = new File( destFolder + '/' + newName );

return saveInFile;
}


function getSVGOptions()
{
	var svgSaveOpts = new ExportOptionsSVG();
							svgSaveOpts.DTD = SVGDTDVersion.SVG1_1;
							svgSaveOpts.embedRasterImages = false;
							svgSaveOpts.cssProperties = SVGCSSPropertyLocation.STYLEATTRIBUTES;
							svgSaveOpts.coordinatePrecision = 3;
							svgSaveOpts.fontType = SVGFontType.SVGFONT;
							svgSaveOpts.documentEncoding = SVGDocumentEncoding.UTF8;
							svgSaveOpts.fontSubsetting = SVGFontSubsetting.None;
							svgSaveOpts.response = false;
							svgSaveOpts.sVGTextOnPath = true;
							svgSaveOpts.slices = false;
							svgSaveOpts.preserveEditability = false;
							svgSaveOpts.sVGAutoKerning = false;
						return svgSaveOpts; }

 Here is an example of a SVG file that was correct converted:

And here now a converted SVG with the new illustrator version, no width or height anymore.

Do anyone have a clue what could be the reason? Must the script be updated?

Thank you very much!
