Default Calendar Not Loading Events After New MM Update

inteeraymee

@sdetweil I have about 5 that are sourced in Google and another 2 or so that are subscription-based (i.e. sports teams).

The way that I am starting MM is via ssh since my monitor is inside a frame up on a wall, making it a challenge to connect directly. The script I use is:

sudo -u rudin-fam
DISPLAY=:0
XAUTHORITY=/home/rudin-fam/.Xauthority
nohup chromium --kiosk http://localhost:8080
–noerrdialogs
–disable-infobars
–disable-session-crashed-bubble
–disable-restore-session-state
>/dev/null 2>&1 &

@inteeraymee that’s the display side, where is the server side?

@sdetweil Hi, I am having the same problem since upgrading this morning (MM v2.35)

5 calendars, all from Google

Platform: Raspberry Pi3 B
OS: Debian GNU/Linux 11 (bullseye)

I haven’t tried regenerating the calendar links, should I?

sdetweil

@hrt13 shouldn’t need to

Are there any errors reported in the console log where you start MagicMirror?

If using pm2, then

pm2 logs —lines=xxx
Xxx is the number of latest lines to display, default 15
You might need 100

@sdetweil Using pm2, I see a lot of “could not expand event” errors. Here’s one:

" [2026-04-02 12:29:21.274] [ERROR] [calendar] Could not expand event “Hockey vs. C”: ical.expandRecurringEvent is not a function"

Thanks

sdetweil

@hrt13 awesome to help could you find that event

curl -sL the_url_for_calendar >somefile.txt

Then edit somefile.txt and search for that title
Copy
Begin:vevent
…
End:vevent

And paste here. In code block
Edit Any info that might identify you, just dont delete any lines

@sdetweil

I think this is it, it may be in the past (I’ll look for a more current one, I didn’t think I was getting events from the past), also, sorry about the ^M’s:

@hrt13 is there one on a repeating schedule?

We shouldn’t expand one if it doesn’t have an rrule

@sdetweil said:

There are some recent repeating events though I’m not sure any show in the logs. I’ll see if I can find some new events. Looking at the logs again, it seems it’s retrieving lots of past events which, of course, wouldn’t show on the calendar. The latest I’ve seen so far is an event from Jan 2026.

@sdetweil this is definitely a repeating schedule

Log file error:
[2026-04-02 19:59:16.671] [ERROR] [calendar] Could not expand event “Tax Day”: ical.expandRecurringEvent is not a function

@hrt13 hmm. A repeating event has one vevent, with an rrule line that describes how it repeats
