do you see any errors in browser console/network or nextcloud.log?

[ralfbgithub]

no relevant entries in the nextcloud.log
Edge console: no errors but the warning: index.es.js:2337 Proxying an event bus of version 3.1.0 with 1.3.0

I also updated to NC 27.1.0 and Calendar 4.5.0

(Updated the docker container https://github.com/linuxserver/docker-nextcloud which automatically updated the app as well)

My widget is not empty, but it has another issue:
For re-occuring events, it does not show when it will happen next, but when it was created- which makes it very confusing.
Same with the contact birthdays (yellow).

Blue = last day of the month
1st purple = every saturday, shown 1 time for the rest of month
2nd purple = regular event, no reoccurence
yellow = birthday
I do think they are sorted by the time they were created, but I am not sure.

when creating a new event for next week, I do get this:

It has the right descriptive text to it (actual scheduled time, not when it was created) but it is displayed in last place, even though it is the first event to occur.

Talked to @st3iny. This is the same issue we have for mobile widget before: #4813. Bringing the mobile data to the browser via #5417 also gives us the bugs.

Needs improvement on the recurrence expansion as discussed with @st3iny

I'm experiencing the same problem (empty widget) after upgrading from 26.0.7 to 27.1.1.
But in my case I cannot see any Deck tasks that I usually can see (e.g. the Deck tasks with due dates in this next week).
I opened a new issue #5489 because it's different from this case.

[HyperCriSiS]

I have similar issues.
Since the calendar app and contacts app were updated two days ago, both of them do not load anymore.

Nothing related is in the logs.

[ChristophWurst]

Fixed by nextcloud/server#40541?

[st3iny]

The issue mentioned by @naelfe should be fixed by the linked issue (showing wrong dates/times). However, showing no event is a different issue I think.

Also note that there are more fixes regarding the ordering in #5486.

EDIT: I was able to create such a situation and can confirm that it is fixed by the server PR.

I am running NC 27.1.2 and still have the empty widget issue. Should this fix here already be included or will it come in a future version of NC? If so, which one? Thanks!

It should be included in 27.1.2.
