ReferenceError: Can't find variable: JSCocoaController

[shankarcabus]

I'm trying to run this plugin, but it has an error that prevents works.

Sketch[23432]: -[NSArray length] is deprecated . Please call -[NSArray count] instead
Sync Symbol (Sketch Plugin)[23432]: ReferenceError: Can't find variable: JSCocoaController.
Sketch[23432]: Exception: {

That occurs in this function:

function getLayerGroupsByTag(parent, tag) {
  var all = [parent layers];
  // sometimes layers returns an instance of JSCocoaController, I'm not sure why
  if([all class] === JSCocoaController) return [];

  var groups = filterNSArray(all, isGroup),
      tagged = [],
      notTagged = [];

  groups.forEach(function(group) {
    var name = [group name];
    var groupTag = name.match(tagPattern);
    if(groupTag && groupTag[1] === tag) {
      tagged.push(group);
    } else {
      nested = getLayerGroupsByTag(group, tag);
      Array.prototype.push.apply(tagged, nested);
    }
  });

  return tagged;
}

"// sometimes layers returns an instance of JSCocoaController, I'm not sure why"

Do you have any idea why this is always happening?
