Syncing Google Sheets to Calendar App Script - google-apps-script

Question

I have the below script and keep getting the error 'Cannot find method createEvent(number,string,string).' I can't figure out what's wrong. Any ideas?
function createCalendarEvent() {
var sheet = SpreadsheetApp.getActiveSheet();
var startRow = 2;
var numRows = sheet.getLastRow();
var numColumns = sheet.getLastColumn();
var dataRange = sheet.getRange(startRow, 1, numRows-1, numColumns);
var data = dataRange.getValues();
var complete = "Done";
for (var i = 0; i < data.length; ++i) {
var row = data[i];
var aname = row[2]; //Agent
var cname = row[3]; //Client Name
var country = row[4]; //Client Country
var phone = row[5]; //Phone Number
var deposit = row[6]; //Type of Deposit
var ewallet = row[7]; //Processor/eWallet
var method = row[8]; //Deposit Method
var amount = row[9]; //Amount/Percent
var date = new Date(row[10]); //Date of Next Contact
var target = row[12]; //Target Amount
var history = row[13]; //Deposit History incl. dates
var currency = row[14]; //Currency
var comments = row[15]; //Comments
var stime = new Date (row[17]);
var etime = new Date (row[18]);
var added = row[19]; //Added to calendar
if (added != complete) {
var currentCell = sheet.getRange(startRow + i, numColumns);
var event = CalendarApp.getDefaultCalendar().createEvent(cname, stime, etime);
currentCell.setValue(complete)};
}
}

This error means that it cannot find that method, probably because you're using wrong arguments to the function createEvent(String,Date,Date) (see documentation here).
You are using function createEvent(number,String,String), which doesn't exist.
Your first variable cname should be transformed to string, and what you are also seing in the error is that 2nd and 3rd parameter are as string, while they should be dates.
The proper solution would be to transform starttime and endtime to date, and that depends on how is the format of your string date.
