Invalid Response 207 Mutli-Status returning 200

[hscissors]

Baikal version: 6.3.0

Expected behaviour: Using DavDroid 1.6.5-ose, syncing address book and calendar should work

Current behaviour: After upgrading Baikal to 6.3.0, I'm getting errors from DavDroid when I go to sync. This ticket was posted before, but closed when PHP 7.3. was not supported: #615. Here is the complete error from DavDroid:

I use DAVx⁵

DavDroid and DAVx5 are the same thing.

Did you visit the admin interface in a browser after upgrading?

Did you visit the admin interface in a browser after upgrading?

I did. I proceeded with the upgrade process and it now says "Baikal is running alright"

[WeT-Klb]

May i ask if there is really Baikal 6.3.0? I am running Baikal 0.6.0...

[ByteHamster]

You could try to enable debug logging in DavDroid and then look for the content of Baikal's response in logcat.

In my case, this issue was caused by an upgrade of PHP from 7.2 to 7.3 which was done by my web hosting provider without my knowledge. Viewing the offending URL <url>dav.php/principals/polaris/ in a web browser will throw a PHP error that hints at some incompatibility with the break vs. continue statements.

Looks like this was an issue with php 7.3, which is now officially supported. If you still have this problem in recent Baikal versions, feel free to comment and I will re-open the issue.
