When I use a script to get text layer information, this line of code colorDesc.getDouble(stringIDToTypeID('red')) throws an error: 

This functionality may not be available in this version of Photoshop Error. no additional information available

function get_layer_text_info() {

var ref = new ActionReference();

ref.putEnumerated(charIDToTypeID("Lyr "), charIDToTypeID("Ordn"), charIDToTypeID("Trgt"));

var layerDesc = executeActionGet(ref);
var textDesc = layerDesc.getObjectValue(stringIDToTypeID('textKey'));

var layerStyles = textDesc.getList(stringIDToTypeID('textStyleRange'));

var textContents = textDesc.getString(stringIDToTypeID('textKey'));
var textInfoList = [];

alert("layerStyles.count:" + layerStyles.count)

for (var i = 0; i < layerStyles.count; i++) {

var textStyleRange = layerStyles.getObjectValue(i);

var from = textStyleRange.getInteger(stringIDToTypeID('from'));

var to = textStyleRange.getInteger(stringIDToTypeID('to'));

var textStyle = textStyleRange.getObjectValue(stringIDToTypeID('textStyle'));

var color;
if (textStyle.hasKey(stringIDToTypeID("color"))) {

var colorDesc = textStyle.getObjectValue(stringIDToTypeID('color'));

alert("test" )

var red = colorDesc.getDouble(stringIDToTypeID('red'));
var green = colorDesc.getDouble(stringIDToTypeID('green'));
var blue = colorDesc.getDouble(stringIDToTypeID('blue'));
color = red + "," + green + "," + blue;
} else {
color = null;
}

}

The reason has been found, it's because some keys do not exist.For example, red and size.
