Getting weird error: "General Photoshop error occurred".

Question

Hi Guys,
I am trying to get the info(font, color, alignment etc.)  of text kind layer in Photoshop CC. My script is as follows,
var textLayer = activeDocument.activeLayer.textItem;
var fontName = textLayer.font;
try{
     var textColor = "R: " + textLayer.color.rgb.red + " G: " + textLayer.color.rgb.green + " B: " + textLayer.color.rgb.blue;
catch(e){alert(e);}
try
     var textAlignment = textLayer.justification.toString();
catch(e){alert(e);}
On setting the color value R - 0, B - 0 and G - 0 or alignment 'Left' and create a text layer after this. I encountered an error
"Error: General Photshop error occurred. This functionality may not be available in this version of Photoshop.
     - <no additional information available> "
If I set some other color value and other alignment and create the text and get its info, script works fine.
Or If I change the values and revert it back to 'Left' alignment and R-0, B-0 and G-0 then I am able to get the values with the above script.
I get this error at first time only and after that script works fine
I also run this script with CS5 version, Its working fine there. But I don't know why I am getting this error in CC version.
Am I doing something wrong here or Is it some issue with Photoshop CC.
Any help would be appriciated.
Thanks..

Is your text layer using a layer style? If so, this routine should find the font and color in use.
var fontsInUse = [];
var colorsInUse = [];
if ( documents.length > 0 ) {
    GetFontUsage( activeDocument.layers, fontsInUse );
          alert( fontsInUse );
    GetColorUsage( activeDocument.layers, colorsInUse );
          alert( colorsInUse );
} else {
          alert( "Please open a document." );
function GetFontUsage( l, f ) {
    for ( var i = 0; i < l.length; i++ ) {
        if ( l[i].typename == "LayerSet" ) {
            GetFontUsage( l[i].layers, f );
        } else if ( l[i].typename == "ArtLayer" && l[i].kind == LayerKind.TEXT  ) {
            try {
                f.push( l[i].textItem.font );
            catch(e) {
                f.push( GetFontUsageFromDescriptor( l[i] ) );
function GetColorUsage( l, f ) {
    for ( var i = 0; i < l.length; i++ ) {
        if ( l[i].typename == "LayerSet" ) {
            GetFontUsage( l[i].layers, f );
        } else if ( l[i].typename == "ArtLayer" && l[i].kind == LayerKind.TEXT  ) {
            try {
                f.push( Math.round(l[i].textItem.color.rgb.red) + ":" +
                        Math.round(l[i].textItem.color.rgb.green) + ":" +
                        Math.round(l[i].textItem.color.rgb.blue));
            catch(e) {
