InDesign JavaScript: MenuActions "action is not enabled" error

Hi ​@Jurre37971467hccf , Here is a capture from the document’s createTOC() method—the 2nd parameter is a replace boolean

While others have mentioned createTOC() should be used, I just wanted to post that I managed to get the menu action to work in the loop by changing the for-loop as follows:

for (var i = mergeDocs.length - 1; i >= 0; i--){
    app.activeDocument = app.documents[i];
    updateTOCs(app.activeDocument);
}

In case it helps anyone.

As Manan mentioned, no need to select anything. In fact, selecting things and invoking menu commands should be done only if there aren’t direct script commands.

createTOC() is a function of the document, not of a text frame.

I suppose you don’t need to either find the TOC frame nor execute the menu. You can call the createTOC method it has an argument which says replacing if set to true should update the existing TOC. See the details at https://www.indesignjs.de/extendscriptAPI/indesign-latest/#Document.html#d1e49740__d1e53775

function updateTOCs(doc) {
    if (!doc) return;

    // Find the text frame named "TOC"
    var tocFrame = doc.textFrames.itemByName("TOC");
    if (!tocFrame.isValid) {
        $.writeln("No text frame named 'TOC' in document: " + doc.name);
        return;
    }

    // Check if this text frame has a TableOfContents object
    if (tocFrame.tablesOfContents.length === 0) {
        $.writeln("No TOC found in text frame 'TOC' in document: " + doc.name);
        return;
    }

    // Update all TOCs in this frame
    for (var i = 0; i < tocFrame.tablesOfContents.length; i++) {
        tocFrame.tablesOfContents[i].update();
        $.writeln("Updated TOC in document: " + doc.name);
    }
}

// Iterate through all open documents
for (var i = 0; i < app.documents.length; i++) {
    updateTOCs(app.documents[i]);
}

Not the best at this - but just to add a few bits see if it works for you now
