Interface error Error loading events from calendar /path_to_sabre/cal.php/calendars/fede/default/
The logfile shows the following error:
[2017-01-06 16:39:41] agendav.WARNING: Received unexpected HTTP code 500 (Server error: `REPORT https://mydomain.de/path_to_sabre/cal.php/calendars/fede/default/` resulted in a `500 Internal Server Error` response: <?xml version="1.0" encoding="utf-8"?> <d:error xmlns:d="DAV:" xmlns:s="http://sabredav.org/ns"> <s:sabredav-version>3 (truncated...) ) for input: Symfony\Component\HttpFoundation\ParameterBag::__set_state(array( 'parameters' => array ( 'calendar' => '/path_to_sabre/cal.php/calendars/fede/default/', 'start' => '2016-12-26', 'end' => '2017-02-06', 'timezone' => 'Europe/Berlin', '_' => '1483717174933', ), )) [] []
The browser tries to load the events from this url:
The calendar itself is loaded by this url:
https://agendav.mydomain.de/calendars?_=1483718855818
It returns the expected JSON calendar object.
Any idea how to fix it? I tried already several hours to fix this issue.
Thanks in advance.
Kind regards
Frederik
