  I need to make a loading animation type arc using JS script, how can I do that?
  I tried this method
  but it gives me error “Object is Invalid”

  app.project.close(CloseOptions.DO_NOT_SAVE_CHANGES);
  app.newProject();
  app.beginUndoGroup("Create Comp");
  var width = 1920;
  var height = 1080;
  var duration = 10;
  var frameRate = 25;
  var bg = [1, 0, 0];
  var arc = [0, 1, 0];
  var comp = app.project.items.addComp("Comp", width, height, 1, duration, frameRate);
  comp.openInViewer();
  var layer = comp.layers.addSolid(bg, "Background", width, height, 1);
  var shapeLayer = comp.layers.addShape();
  shapeLayer.selected = true;
  var shapeGroup = shapeLayer.property("ADBE Root Vectors Group").addProperty("ADBE Vector Group");
  var arc = shapeGroup.property("ADBE Vectors Group").addProperty("ADBE Vector Shape - Ellipse");
  arc.property("ADBE Vector Ellipse Size").setValue([100, 200]);
  var arcFill = shapeGroup.property("ADBE Vectors Group").addProperty("ADBE Vector Graphic - Fill");
  var mask = shapeLayer.property("ADBE Mask Parade").addProperty("ADBE Mask Atom");
  mask.property("ADBE Mask Shape").setValue(arc.property("ADBE Vector Shape"));
  var maskPath = mask.property("ADBE Mask Shape");
  var startAngle = 0;
  var endAngle = 90;
  maskPath.setValueAtTime(0, [width/2, height/2, startAngle]);
  maskPath.setValueAtTime(duration, [width/2, height/2, endAngle]);
  var rotation = shapeLayer.transform.rotation.property("ADBE Vector Rotation");
  rotation.expression = "time * 360";
  app.endUndoGroup();
