I am still trying out Kerio CalDAV with self hosted cal.com version 1.8.3 I get this error in the frontend, when trying to use the "debug" interface:

Something went wrong.

https://URL/api/availability/saschafoerster?dateFrom=2022-07-26T22:00:00Z&dateTo=2022-07-27T21:59:59Z

I get this
{"message":"performance is not defined"}

I am hoping very much to use it cal.com soon WITH our calendars, as without seeing availabilities , it is rather useless. Thank you for looking into it. If I can help debugging or give more information, let me know.

[alishaz-polymath]

Hi @saschafoerster Thank you for the detailed message. I've got Kerio connect for CalDAV lined up soon for testing. As soon as I'm done with it, it should be good to go! 🙏 Thanks for your patience.

[alishaz-polymath]

Just thought I'd explicitly mention, Kerio connect with CalDAV works perfectly now, the entire flow 🙏
So, if anyone faces any issues at all regarding that, please do let me know 😄

[alishaz-polymath]

Zimbra is now fully supported 🚀
Fully tested 🧪 ✅

[rene-mueller]

• Confluence Calendar

would be nice

[alishaz-polymath]

@rene-mueller Added to the list. Will run checks when the time is right and see if we can fully support it 🙂

[chrisgick]

@alishaz-polymath if you need a Confluence Cloud test environment I would be happy to help

[alishaz-polymath]

@chrisgick that would be lovely. Thank you. I think we can explore that over a call instead to ensure the access remains secured.

[alishaz-polymath]

@chrisgick There seems to be an issue with Confluence itself, pertaining to CalDAV (or perhaps their docs)
Firstly, I get the unauthorised error when I try to use username and password basic Auth.
Then I had a look at the deprecation notice (ref below), and a couple of articles where it suggested to use 'username:password' string and convert to base64 and use that for basic authorization instead. When I do that, it just returns empty.
Do you have any ideas regarding this, or perhaps contact who might be able to assist for the same?

[tonybruess]

Fastmail appears to be working now. Was broken last month.

[alishaz-polymath]

@tonybruess we are in talks with Fastmail currently. Our calls were getting Forbidden returned. We aren't fully supporting it yet, tests are being run. Once it is fully supported, you'll see the tick against its name in the description of this ticket 🙂

[alishaz-polymath]

@tonybruess Fastmail was still faulty when rescheduling, however, the PR #5193 should fix that along with fixing Nextcloud rescheduling 🙏

[mtnowl]

I went ahead and created the issue for Fastmail as I am seeing the same issues.

[alishaz-polymath]

Just a gentle nudge here for anyone interested, improving CalDAV UX, reliability and performance: #9990

[qwertiko]

Just to report back: Open-Xchange / OX App Suite works like a charm.

[wzrdtales]

#3457 (comment)

This stopped working again, when the calendar loads first it correctly shows the slots booked, but as soon as you go one page up and back it shows everything as free

[wzrdtales]

Whatever was done, a lot of things got broken instead of fixed again...

Time comes over the XHR call like this, which looks good actually..

[wzrdtales]

This looks like its broken on the frontend side of things, as the initial load contains the very same data.

[wzrdtales]

So it seems some cached things on the second load cause everything to disfunction

[wzrdtales]

the second (seemly cached) result contains more slots, than the freshly fetched. whatevery is going on here in the caching doesn't work

[wzrdtales]

turns out my old fix #3457 (comment)
is still relevant, and the new logic is still broken

see #10818

[pranavburnwal]

Please add tot he list: fastmail.com
Thanks!

Any plans to support proton calendar?

[thfrei]

I'm using Baikal, however, the integration does not seem to work:

1. Once setup, participants could subscribe, however NO emails were sent and no confirmation was shown to the user. The event showed up on the admin side.
2. It did not check if there are any conflicts with my calendar.

Baikal itself worked. I synced my calendar from outlook and double checked with a caldav viewer. They were there.

I'm using the hosted cal.com instance.

[isgroup]

When saving I get this error:

[musselmandev]

When saving I get this error:

I also have been getting the same error for a good while now (I use Baikal)

The error tells us the user little to nothing. I had somthing similar happening in #12329

[emrysal]

@keithwillcode I will pick this up for 3.9

[nepomuc]

Availability check with Baïkal doesn't work, but it's listed as supported here. Is the list up to date?

[apollo-sturdy]

Availability check with Baïkal doesn't work, but it's listed as supported here. Is the list up to date?

I figured out the issue. It is due to this bug: sabre-io/Baikal#1241

For a temporary fix, you can re-create your calendars in iCal (MacOS Calendar app): sabre-io/Baikal#1085 (comment)

[JoshuaKrueger]

I wondered because of mailbox.org support: We are using Open-Xchange / OX App Suite as Calendar-Provider (as mailbox.org is build on), but it doesn't work. Maybe there is a way how to set it up or how does it work with mailbox.org? When I try I only get the error message "r is undefined"

[j23d]

The integration in my SynologyDrive calendar via CalDav stopped working. When I want to reinstall the app I also got the error message "r is undefined".

[jonezy35]

I'm also getting the "r is undefined" error when I try to connect my nextcloud calendar

[jonezy35]

When I inspect the network traffic I see the error "Intercom] The App ID in your code snippet has not been set. Set it to your App ID found in settings to complete installation: https://app.intercom.com/a/apps/_/settings/web"

[jonezy35]

When I open in chrome I get a more thorough error which is "Cannot destructure property 'auth' of 'r' as it is undefined

[Faknit]

For anyone getting errors on Fastmail like "r is undefined" or something like can not restructure to the right of argument -- make sure you are generating an app specific password for cal.com

[musselmandev]

It is very rare for CalDav servers to have a feature like that, but good information regardless, this destructuring error though has been a problem for many services and has been pushed off many times (in my issue it was tagged for the 3.6 milestone at first). I may sit down and try to learn the technologies to see if I can help as I love cal.com but this has been keeping me from fully utilizing it. My issue related to this was even closed as "not planned" (see #12329). Pessimistically, James Musselman 📅 Schedule a Meeting ↗ Sent with Proton Mail secure email.

Can you please add support for PurelyMail.com ?

Wework and DingTalk has some known issue:

[charleslcso]

I am using Radicale. It works perfectly fine.

How to set up self-host cal.com to connect to it? I keep getting Invalid key length when trying to connect using my credentials.

Edit: 24/Jan/2025, my Radicale integration with Cal is working on Add/Delete events. But any events added into the calendar from other means Cal won't pick them up, and these busy slots will be available for Event Types.
