Default Calendar Not Loading Events After New MM Update

hrt13

@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

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

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:

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

Looks like you didn’t update the dependencies after you pulled the new MM version.

Please run node --run install-mm and check again.

trying it now, it is taking a while. Will let you know.
I used mmpm to update, I guess it doesn’t update the dependencies.

A workaround for users still having issues with the calendar. There was a problem with the node-ical package for some events. This has just been fixed with a new node-ical release (v0.26.0).

To use the new version, run this command in the MagicMirror directory:
npm install node-ical@latest.

Note that this will change your package.json and package-lock.json files, which would cause conflicts during the next MagicMirror update. Therefore, also run the following to restore them:
git restore package*.json

You will then have v0.26.0 installed - the package.json file say otherwise, but that doesn’t matter.

Please give some feedback if that helps :-)
