Problem default calendar module

[2hdlockness]

Hello, I just updated my mm, I was 2 or 3 versions late…

I am encountering a problem in the default calendar module with the caldav.icloud calendars.
I have quite a few errors like this :

[2026-01-27 13:57:15.127] [ERROR] [calendar] Moment Timezone has no data for GMT+0100. See http://momentjs.com/timezone/docs/#/data-loading/.

I should point out that the calendars are still well displayed by the mirror.

Thanks for seeing

That error is just log noise. It doesn’t affect anything.

This is a known warning related to Moment Timezone data, not a breaking error. Since your calendars are displaying correctly, it’s mostly harmless. Updating or reinstalling moment-timezone, or switching the calendar config to use a standard timezone like Europe/Paris instead of GMT+0100, usually clears it.
