How can I correctly move unexpanded Compound Shapes in Illustrator using a script?

[Aprking]

When I try to move and scale selected objects in Illustrator using a script, the unexpanded Compound Shapes cannot be moved correctly, while other objects or groups (including unexpanded Compound Shapes) can be moved correctly. Can anyone guide me on how to modify the JSX script to properly move these objects?

var doc = app.activeDocument;
var selection = doc.selection;

var moveX = 10; 
var moveY = 20;
var scaleX = 0.9;
var scaleY = 0.8;

for (var i = 0; i < selection.length; i++) {
  var item = selection[i];

  if (item.parent instanceof GroupItem) {
    continue;
  }

  item.resize(
    scaleX * 100, // x
    scaleY * 100, // y
    true, // changePositions
    true, // changeFillPatterns_value
    true, // changeFillGradients
    true, // changeStrokePattern
    1 ? Math.sqrt(scaleX * scaleY) * 100 : 100,
    Transformation.TOPLEFT
  );
  item.left += moveX;
  item.top -= moveY;
}

Try changing this statement

  if (item.parent instanceof GroupItem) {
    continue;
  }

to

  if (item.parent.typename == "PluginItem" || 
      item.parent.typename == "GroupItem") {
    continue;
  }

Thank you for your help! However, the code still hasn't solved this problem.

I'm going to take a wild guess. Inside the compound shape, you have not only individual paths, but also groups of paths? Can you show a screenshot of the contents of Compound Shape?

 Your guess proves that you are very intelligent. This test file does indeed contain PluginItem, path, CompoundPathItem, and GroupItem, so there are always some objects that cannot be moved or scaled correctly.

I realized what was going on. You ran into an ExtendScript bug, and there are a lot of them. If a Compound Shape contains a Group of objects or a Compound Path (orange labels), the script skips these objects and processes only simple <Path> objects.

I would like to say that there is a workaround for this bug, which requires manual selection of only <Path> inside the Compound Shape: https://aiscripts.medium.com/compound-shape-mess-6b6c44e8c08. But your task is to process all selected objects in a FOR loop, so I don't see a good solution here.

Thank you for your reply. I'm trying to separate the GroupItem and process it separately, and there is always a solution. Also, looking forward to a master appearing.
