Calendar has stopped working

[Jonsar]

@sdetweil Your help is greatly appreciated. It really is a great feature we constantly use for the family to keep everyone informed. If you can suggest a fix, that would be awesome.

@Jonsar looking at it… no idea yet

[sdetweil]

@Jonsar ok, fun time… MS screws us again

they changed the format of the timezone reporting…lovely

not our code, but the calendar parser we use (that I fixed the last 2 times)

workaround

cd ~/MagicMirror/node_modules/node-ical

nano ical.js , scroll down to line 120
delete the whole line and paste in the new one (cursor has to be on that line to paste it there)

change this (line 120 is the code, 119 is the comment)

  // If this is the custom timezone from MS Outlook
  if (tz === 'tzone://Microsoft/Custom' ) {

to this

  // If this is the custom timezone from MS Outlook
  if (tz === 'tzone://Microsoft/Custom' || tz === 'Customized Time Zone' || tz.startsWith('tzone://Microsoft/')) {

also need to fix our code

cd ~/MagicMirror/modules/default/calendar

nano calendarutils.js

change this , line 518

	getIanaTZFromMS: function (msTZName) {
		// Get hash entry

to this

	getIanaTZFromMS: function (msTZName) {
		if(msTZName ==='Customized Time Zone'){
			return moment.tz.guess()
		}
		// Get hash entry

Thanks for this. It didn’t exactly work. It definitely got further than before but I ended up with this error.

@Jonsar can u show me the cal event data in the logs right before the error?

@sdetweil said in Calendar has stopped working:

|| tz === ‘Customized Time Zone’

I see there were two place in ical.js

and there is a timezone like this

‘Customized Time Zone 1’

so this will fail

tz === 'Customized Time Zone'

change to this

 tz.startsWith('Customized Time Zone')

in all three places … 2 in node ical.j one in caldendarutils.js

@sdetweil Thank you, but I can only find 1 place in ical.js. There is one place in calendarutils.js but it is:
if(msTZName === ‘Customized Time Zone’){

The whole error I get is:

yes, I said above that there were actually 2… in ical.js
and to make the second look like the 1st

yes, in calendarutils, 1, which I gave instructions to change

if(msTZName.startsWith(‘Customized Time Zone’){

[Jonsar]

@sdetweil Sorry, I missed the second one in ical.js. It works now! Thanks so much for your help.
