[Davical-general] error: The calendar-query report must be run against a calendar or a scheduling collection

[Giuseppe S. <giu...@sg...>]

Hello,
I just moved Davical from one old machine to a new hardware and updated from
debian 12 (davical version 1.1.12-2) to debian 13 (davical version 1.1.12-
2.1). Davical is behind nginx and uses postgresql locally, as before. The
database has been copied to the new machine, as well. Old postgresql was
version 15, new version is 17. Nginx web site configuration was copied as
is. PHP changed from 8.2 to 8.4. The administration web interface works, all
users are authenticated.

But... when synchronizing calendars from clients, we get this error message
in nginx log (i replaced user and host names):

2026/02/16 09:50:22 [error] 18395#18395: *2373 FastCGI sent in stderr: "

while reading response header from upstream, client: 79.X.Y.Z, server: cal.$mydomain, request: "REPORT /caldav.php/$myuser/calendar/ HTTP/2.0",

Do you have idea of what could be the problem or how to identify it?

Thank you very much,
Giuseppe
