Steps to reproduce

Enable calendar (very old install)

Expected behaviour

Calendar should start

Actual behaviour

Calendar sidebar shows existing calendars (generated from Deck instances) with spinning icons to the side. The calendar is not populated with any data, though new data can be entered. The new data is not populated.

Calendars just enabled (never enabled before) so no events in the calendars. Nothing in the NC logs. Error in JS console is lots of

"l['{DAV:}getcontenttype'] is undefined TypeError: l['{DAV:}getcontenttype'] is undefined"
value davCollection.js:353
value davCollection.js:338
t calendar.js:154
u runtime.js:63

For anyone else that ends up here take a look at https://github.com/nextcloud/calendar/issues/3858

the-moog commented 2 years ago

I've looked at my oc_properties and the table is completely empty. The problem persists.

the-moog commented 2 years ago

I've upgraded to NC 23.0.1 and the problem persists.

pelaxa commented 2 years ago

I do not think that oc_properties should be empty entirely.

the-moog commented 2 years ago

Any update on this issue. Tried latest NC server (23.0.2) and still no joy.

Tried deleting all Deck releated data. Removed completely Deck, Calendar, Appointments and d/l + reinstall. The old data persisted. (Surely removing an app should reset it's database??)

Looking at Firefox debug console I see the following after a refresh of the calendar page. "l['{DAV:}getcontenttype'] is undefined TypeError: l['{DAV:}getcontenttype'] is undefined"

That seems to relate to: nextcloud/calendar#3551 and nextcloud/calendar#3858

the-moog commented 2 years ago

Interesting: Looking at the same issue, but in Edge dev tools. I get the error "Cannot read properties of undefined (reading 'split') TypeError: Cannot read properties of undefined (reading 'split')" which is different to FF where the the error is: "l['{DAV:}getcontenttype'] is undefined TypeError: l['{DAV:}getcontenttype'] is undefined"

Both from line 353 of davCollection.js , which reads "const contentType = props['{DAV:}getcontenttype'].split(';')[0];"

That explains why some people report one error, others report a different error.

Updated to NC 24.0.2 - issues persist. Same errors as before in JS console (or similar) on all browsers.

FF: "l['{DAV:}resourcetype'] is undefined TypeError: l['{DAV:}resourcetype'] is undefined" Edge: "main.js:6115 Cannot read properties of undefined (reading 'find') TypeError: Cannot read properties of undefined (reading 'find')"

pwnoobz commented 1 year ago

I can confirm the calendar hangs forever. Latest update here.

the-moog commented 1 year ago

Same issue on NC25.0.1 but the errors have completely changed.

szaimen commented 1 year ago

Hi, please update to 24.0.9 or better 25.0.3 and report back if it fixes the issue. Thank you!

My goal is to add a label like e.g. 25-feedback to this ticket of an up-to-date major Nextcloud version where the bug could be reproduced. However this is not going to work without your help. So thanks for all your effort!

If you don't manage to reproduce the issue in time and the issue gets closed but you can reproduce the issue afterwards, feel free to create a new bug report with up-to-date information by following this link: https://github.com/nextcloud/server/issues/new?assignees=&labels=bug%2C0.+Needs+triage&template=BUG_REPORT.yml&title=%5BBug%5D%3A+

the-moog commented 1 year ago

Updated from 25.0.2 to 25.0.3. Behavior the same though I seem to have more errors in the Firefox JS console.

@the-moog Are you using external CalDAV clients to sync your Nextcloud calendars? Also, please confirm that cron jobs are working properly.

This might also be an issue with some reverse proxy: Please click on the button from the screenshot and open the copied link in a new tab. What do you see on the page?

the-moog commented 1 year ago

@st3iny Thanks for taking an interest in this issue at last.

My answers:

No external CALDAV. Copy of address as requested: https://nextcloud./remote.php/dav Background jobs are executed by Cron and work fine. File DAV also works fine.

FYI The calendar has not worked for us in a very, very long time. I would say at least 3 years, but probably longer. On the systems which exhibit this issue I have installed/removed the calendar extension and various related components numerous times (over all that time) without much change. Wasted rather a lot of time on this one.... We currently just work without this or any related features - which is a pity as we could use them. A ground up re-install is not really an option. In any case I really really think it would not work.

Clearly it is something with the way our install is configured or everybody would have this issue. But it seems others do have this issue on occasion, though it seems not for the same reason (or they give up and start over). Perhaps something in the server base image or something to do with the VPS provider.....

In the browser JS console I just see obfusticated JS code. I am guessing this is TS->JS generated?

Happy to get a debug env working if somebody will tell me how. I've done a bit of TS/JS coding in the past. Sadly, though I've tried a few time, I've never managed to work out how to debug a live system with the relevant source tree present, remotely.

I think part of the issue in resolving this is that the calendar is a plugin so it's very unclear if the probem with the plugin or the core code (or both). Each community has at some point in the past pushed the issue to the other.

The error at the failure point is always the same, an attempt to de-reference an unset JS variable.

Different browsers give similar errors but at different points in the same code. I think that's more to do with the way their respecitve debuggers and/or interpreters work and how they handle errors rather than the actual code itself.

Oberlurch3000 commented 1 year ago

For me running: "clear-php-opcache" and "nc-fix-permissions" at nextcloudPi fixed the problem after reloading the web page. I had infinite loading screen at calendar app and missing all contacts at contacts app.

btittelbach commented 8 months ago

I currently have this issue as well:

Calendar App Version: 4.6.2 Nextcloud Version: 27.1.5 Database: Postgresql 15

Observations

Dav Server and external Clients are completely fine
ical events when exported look completely fine
only Nextcloud Calender App hangs and FREEZES the browser window
- and ONLY in month view
- and ONLY if viewing a month where many (>16?) concurrent and/or overlapping multiday events are in the calendar that wrap around at least two months (or years)
deleting some entries, solves the problem. Does not matter which entries, just reducing the number helps.
That is however no solution, as the entries need to be there

joshtrichards commented 7 months ago

@the-moog Can your share a snapshot of your Network tab from your browser console when reproducing this?

Also anything non-standard about your web server config for Nextcloud?

the-moog commented 7 months ago

@joshtrichards I've kind of decided that feature is never going to work. And those that were using it have drifted off to other solutions (MSOffice365) due to the Calendar never working, despite multiple re-installs. The same thing happens on multiple installs on multiple servers (in fact I've never seen it work since I started using NC - I was on OC until the fork). All I can think is I use Apache rather than Nginx. Servers are stock Ubuntu server (2018.04 iirc originally but upgraded since) Infrastucture is dedicated VPS hosted in Germany with a 10G network connection (not oversubscribed/resource limited). As for the config it's textbook. I've not really got time now to look into this as there would be no benefit as nobody is using it. When I was looking at it I wasted hours trying to understand the code flow.....
