copyBoard method for Meteor with problems.

copyBoard.js

  // The callback should take a error object and a boardId.
	copyBoard: function(options) {
    options = options || {};
    if (!(typeof options.boardId === "string" && options.boardId.length)) {
      throw new Meteor.Error(400, "Required parameter missing");
		}
		if (!options.callback) {
      throw new Meteor.Error(400, "Required parameter missing");			
		}
    if (! this.userId)
      throw new Meteor.Error(403, "You must be logged in");
			
		// Create new board.
		var currentBoard = Boards.findOne({ _id: options.boardId });
		// Drop the id from the board and insert that as the new board.
		delete currentBoard["_id"];
		console.log("Inserting board:", currentBoard);
		Boards.insert(currentBoard, 
			function(error, newBoardId) {
				if (!error) {
					console.log("Inserted id:", newBoardId);
					var allBoards = Boards.find().fetch();
		
					// Creates duplicates of the records, giving them have different _ids, then makes
					// changes specified in the recordTransformer function to them.
					function duplicateRecords(recordArray, collection, recordTransformer) {
						// Scrub the _ids out of the records.
						var idLessRecords = _.map(recordArray, function(record) {

							return recordTransformer(record);
						});
	
						collection.insert(idLessRecords);
					}
		
					var userId = this.userId;
					function updateBoardAndOwnerInRecord(record) {
