Calendar not loading after update to 2.26

[sdetweil]

@avano alomao try this

cd ~/MagicMirror
npm install electron@28.1.1

@sdetweil I tried both the above suggestions, but no change.

However, I enabled the DEBUG mode and saw that some events in my calendar took a lot longer to be processed. These events are open-ended events in my Google calendar. They look like the below extract. So I removed them temporarily.

I no longer get the Warning: vkCreateInstance: Found no drivers!

The calendar now loads.
But I’ll try to re-create them and see if they are formatted the same way.

@avano cool… any chance u can find the VEVENT in the downloaded ICS file

curl -sL cal_url >someicsfile.txt

my fix should remove all those null entries…

and the vulcan thing is a bug in electron putting out a spurious message

can u edit

~/MagicMirror/modules/default/calendar/calendarfetcherutils.js

and look at line 293

					let dates = rule.between(pastLocal, futureLocal, true, limitFunction);
					Log.debug(`Title: ${event.summary}, with dates: ${JSON.stringify(dates)}`);
					dates = dates.filter((d) => {   // my fix starts here    
						if (JSON.stringify(d) === "null") return false;
						else return true;
					});

@sdetweil I put back an open-ended event into my calendar, here is the VEVENT: (the calendar no longer loads, and the warning is back.)

BEGIN:VEVENT
DTSTART;TZID=Europe/Zurich:20240119T100000
DTEND;TZID=Europe/Zurich:20240119T110000

END:VEVENT

I looked into ~/MagicMirror/modules/default/calendar/calendarfetcherutils.js line 293, it looks like I have your fix already:

Log.debug(`Search for recurring events between: ${pastLocal} and ${futureLocal}`);
let dates = rule.between(pastLocal, futureLocal, true, limitFunction);
Log.debug(`Title: ${event.summary}, with dates: ${JSON.stringify(dates)}`);
dates = dates.filter((d) => {
	if (JSON.stringify(d) === "null") return false;
	else return true;
});

Apologies, I must have refreshed something since my last post, because the calendar now loads including my open-ended event.
I updated my config.js back to it’s initial state (i.e. uncommenting all our tests, removed DEBUG mode), and I started the app with PM2 instead of “npm start”, but I can’t think of any other change I made.

Do you want me to run some more tests to try and identify the actual issue?
In any case, thanks for all your help.

[sdetweil]

@avano no. I’ll look at the event and set it back to 2013 start.

I put in the fix cause there is a bug in rule with old events, where the count has expired…
