Question

I am stuck.. Error is thrown # Line 63 and sometimes at line 50. Both using the appendTableRow() method. I can't find anything wrong.
row3.appendTableCell(entryDesc)

Answer 1

I found a solution, it appears that: body.appendTableCell(); doesn't handle line breaks "\n". When the script was importing a multi-line event description from the calendar I would get a "server error" message. Adding split('\n') to the description row solved the problem. This worked: body.appendTableCell(data).split("\n");
Finished code:
var entryDesc = (events[i].getDescription().length > 1) ? events[i].getDescription() : "";
if (entryDesc) {
var row3 = entriesTable.appendTableRow();
row3.appendTableCell("");
row3.appendTableCell(entryDesc.split("\n"))
.setAttributes(entryDescriptionStyle);
}

Answer 2

I don't have a complete answer but I thought it might be interesting in the mean time to show a version that works without the event description.
I changed the calculation of total time that didn't work either.
Code can be tested on any default calendar using test function.
function test(){
//dateStart,dateFinish,doc
var doc = DocumentApp.getActiveDocument();
var dateStart = new Date('January 1, 2014');
var dateFinish = new Date('April 1, 2014')
importDataToTS (dateStart,dateFinish,doc);
}
function importDataToTS (dateStart,dateFinish,doc) {
if (!dateStart) {
var dateStart = new Date('January 1, 2014');
}
var cal = CalendarApp.getDefaultCalendar();
var events = cal.getEvents(dateStart, dateFinish);
var oldDate = new Date(dateStart.getFullYear(), dateStart.getMonth(), dateStart.getDate() - 1);
var paragraph = "";
var totalHoursWorked = 0
// START --- Text element styles
// Date
var entryDateStyle = {};
entryDateStyle[DocumentApp.Attribute.BOLD] = true;
entryDateStyle[DocumentApp.Attribute.FONT_SIZE] = 18;
// Title
var entryTitleStyle = {};
entryTitleStyle[DocumentApp.Attribute.FONT_SIZE] = 14;
// entryTimes
var entryTimesStyle = {};
entryTimesStyle[DocumentApp.Attribute.BOLD] = true;
entryTimesStyle[DocumentApp.Attribute.FONT_SIZE] = 12;
// entryDescription
var entryDescriptionStyle = {};
entryDescriptionStyle[DocumentApp.Attribute.ITALIC] = true;
entryDescriptionStyle[DocumentApp.Attribute.FONT_SIZE] = 10;
// END --- Text element styles
var entriesTable = doc.appendTable();
Logger.log('events.length = '+events.length);
for (var i = 0; i <events.length; i++) {
var entryDate = events[i].getStartTime();
if (i > 0) {
oldDate = (events[i-1].getStartTime());
}
Logger.log('i = '+i);
// If it's a new day add a full width cell
if (entryDate.getDate() > oldDate.getDate()) {
var row1 = entriesTable.appendTableRow();
row1.appendTableCell(shortDate(entryDate,4))
.setAttributes(entryDateStyle);
}
// Add title, start/end times & hours worked
var entryTitle = events[i].getTitle();
var entryTimes = shortTime(events[i].getStartTime(),2) + " - " + shortTime(events[i].getEndTime(),2);
var entryHoursWorked = (events[i].getEndTime().getTime() - events[i].getStartTime().getTime())/(1000*60*60) + "hr(s)";
var row2 = entriesTable.appendTableRow();
row2.appendTableCell(entryTitle)
.setAttributes(entryTitleStyle);
row2.appendTableCell(entryTimes + "\t\t" + entryHoursWorked)
.setAttributes(entryTimesStyle);
// Add entry description
var entryDesc = (events[i].getDescription().length > 2) ? events[i].getDescription() : "";
totalHoursWorked += Number(entryHoursWorked.replace(/\D/g,''));
if (i === (events.length - 1)) {
var lastRow = entriesTable.appendTableRow();
lastRow.appendTableCell("Total Hours: " + totalHoursWorked+' Hours');
}
}
for (var i = 0; i in entriesTable; i++) {
for (var j = 0; j in entriesTable[i]; j++) {
Logger.log(i + ":" + j + " " + entriesTable[i][j].toString());
}
}
doc.saveAndClose();
}
