Getting comments from range in Google Script

I'm trying to parse a Google spreadsheet, that holds comments within merged cells.

I'm trying to extract and create 'shift' objects from the range:

/**    
* Return shifts object
* @contextSheet the sheet that is being parsed
* @baseTime the relative time that represent day 1
*/
extractShiftsFromSpreadSheet : function (contextSheet,baseTime) {
  var shifts = [];
  var ss = contextSheet;
  //For each day of the week:
  for(var dayIndex = 1; dayIndex <7 ; dayIndex++) {        
    var day = Script.Util.getDayByNum(dayIndex-1);  //Convert day num to day string
    var ShiftRangePerDay = Script.SpreadSheet.getShiftRangeByDay(ss,day);
    var notes = ShiftRangePerDay.getComments();
    var rows = ShiftRangePerDay.getNumRows();
    var cols = ShiftRangePerDay.getNumColumns();
    var values = ShiftRangePerDay.getValues();
    var startTime;
    var endTime;
    var note = '';
    for (i = 0; i <= rows - 1; i++) {
      for (j = 0; j <= cols - 1; j++) {
        //var cell = values[i][j];
        var studentName = values[i][j].trim();
        //if the cell value isn't a student, move on to the next cell
        if(!Script.Util.isValidStudent(studentName)) continue;
        // otherwise, it is a valid student shift: create it!

        try {
          note = notes[i][j];
        }
        catch(err) {
          //skip

        }
        if(note !== '' && typeof note !== 'undefined') {
          Logger.log("note found for "+studentName+"."  +" note:"+ note);
        }

now, the var notes = ShiftRangePerDay.getComments(); line should return a String[][] object and I should be able to read from it, according to the following API reference: https://developers.google.com/apps-script/reference/spreadsheet/range?hl=en#getComments()

However, it does not work. I've tried using getComments() , getNotes() and even getCell(i,j).getNote(). Nothing seems to be working here.

It seems that I've missed something here, and I would love to hear what you think of it.

The methods dealing with comments are broken, as reported in Issue 2566. Star it to receive updates, and to help drive up the priority of a fix.

If you use Notes (not Comments), you should find that your code works. Notes are less user-friendly in the Sheets UI, but at least they (sorta) work with scripts.
