Default Calendar Not Loading Events After New MM Update

[HeikoGr]

i filed an issue: https://github.com/jens-maus/node-ical/issues/495

it could be an edge case on my side.
@inteeraymee by any chance: did you use emClient anytime in the past?

only workaround for my setup is to pin to v2.34.0 .
Updating the calendars might be the best solution for me…

@HeikoGr we originally never parsed the vtimezone sections

@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
