Set label on a paragraphstyle

Now I am getting this error please find the code which I have used

function applyLabelToStyle1() {
var myDoc = app.documents[0];
var myParas = myDoc.stories.everyItem().paragraphs.everyItem().getElements();
var myPage = myDoc.pages;

for(var i=0; i<myParas.length; i++) {
app.select(myParas[i]);
var paraStyleName = myDoc.selection[0].appliedParagraphStyle.name;

if (paraStyleName == "MM_NL_Preis") {
app.selection[0].label = "TODO";
}
}
}

applyLabelToStyle1();

If you want to start out from the applied paragraph style of a text selection, you could do:

app.selection[0].appliedParagraphStyle.insertLabel( "key" , "value" );

But that would not help much if you want to "label" paragraphs, formatted text, where a certain paragraph style is applied.

There is no "label" for text.

Instead:

You could use the property previewColor of a paragraph style that is not available from the GUI.

Marc Autret once built a full script around this feature, StyLighter:

StyLighter is still working with InDesign 2023.

You could highlight paragraphs in your text where a distinct paragraph style is applied to.

If you want to set label on paragraphstyle then you can use the following code

var ps = app.documents[0].paragraphStyles.itemByName("Name of your style")
ps.insertLabel("key", "value")

P.S.:- This will not work with styles inside groups.
