Problems syncing with iPhone

[Rainbird-1]

Is it possible that synchronization with the iPhone no longer works with 0.9.3?

Ubuntu Server 22.04.1 LTS Apache2 (2.4.54) php 8.2.0 phpmyadmin 5.2.0 MariaDB 10.6.11 Baikal 0.9.3

I can normally sync my contacts from Outlook to my Baikal Server, but not to the iPhone (iOS 16.1.2). I reinstalled the Baikal server and now I'm wondering why no contacts arrive on the iPhone. With the appointments it works quite normally.

https://ip/baikal/html/card.php/principals/user/

without function.

https://ip/baikal/html/cal.php/principals/user/

goes quite normally.

Does somebody has any idea?

Hi Rainbird-1,

I have a similar issue. Carddav broken, Caldav works.

I think it is related to php8.2 and Baikal 0.9.3. I recently upgraded to php8.2 and a few weeks ago it worked (when I had php7.4)

Can you check your webserver logs for "Creation of dynamic property ... is deprecated" (details at the end) I'm still investigating, but I think this is the right direction.

The full log entry looks like: 2023/01/09 20:19:27 [error] xxxxx#xxxxx: *xxx FastCGI sent in stderr: "PHP message: ErrorException: Creation of dynamic property Sabre\CardDAV\Xml\Request\AddressBookMultiGetReport::$addressDataProperties is deprecated in xxxxxxxxxx/nginx/html/baikal/vendor/sabre/dav/lib/CardDAV/Xml/Request/AddressBookMultiGetReport.php:104

Unfortunately, I can no longer deliver the corresponding logs because I switched back to the following installation:

Ubuntu Server 22.04.1 LTS Apache 2.4.52 PHP 8.1.2-1 phpMyAdmin 5.2.0 MariaDB 10.6.11 Baikal 0.9.3

Since the request has not yet been answered and I am dependent on my calendar and contacts on the server.

Sorry!

But with the change everything works again. I could well imagine that it is PHP (too new version).

Nevertheless, thank you very much for the feedback!

[WalterFaber]

Thank you anyway! I made some progress with my investigations and now I'm quite sure the root cause is the error message I mentioned in my comment above "PHP message: ErrorException: Creation of dynamic property Sabre\CardDAV\Xml\Request\AddressBookMultiGetReport::$addressDataProperties is deprecated".

Even if this should be no issue for code execution according to this site https://php.watch/versions/8.2/dynamic-properties-deprecated, the application's error handling has also some impact on outcome. And it seems like Baikal ends up with a http 500 error message, even if the deprecated message does not imply that.

I was able to extract a request from Thunderbird's carddav implementation via debug console...

@ Development team - could you give a rough estimate when you are going to add PHP8.2 compatibility to Baikal? I'm just asking because I think about downgrading to php8.1.

Thank you in advance and also thank you very much for your efforts with this great software!

To add a data point, I had the exact same problem. I'm running a local (Apache) web server on MacOS and for the last few months found my iPhone wasn't syncing contacts to Baïkal. I was running PHP8.2. I didn't have time to figure out what was going on until today, and came across this issue. I found the exact log entries that @WalterFaber did, and so downgraded to PHP8.1. Immediately, the iPhone started syncing again. I'm fine running PHP8.1, but it would be great if this issue could eventually be addressed. And thanks for all your great work on Baïkal!

Hi guys, issue on CalDAV with an iPhone under iOS16, not showing any calendar. Paradaxally, CardDAV seems to work fine. Found this forum: https://developer.apple.com/forums/thread/691818 Has anyone met the same issue?

upgrading dav to 4.5.1 fixes this issue. Download code from https://github.com/sabre-io/dav/releases/tag/4.5.1. Copy new code to baikal/vendor/sabre/dav.

/var/www/html/baikal/vendor/sabre$ sudo cp -r dav-4.5.1/* dav

Since November 18th, 2023 I have had a different configuration for the installations which has worked since then.

Ubuntu Server 22.04.3 LTS Apache 2.4.58 PHP 8.3.0 phpMyAdmin 5.2.1 MariaDB 10.11.6 Baikal 0.9.4

Nevertheless, thank you very much for the information!
