when i parse this via icalendar.Calendar.from_ical(myresponse_string) i get the following error:

"Traceback (most recent call last):

@RainerWahnsinn would you mind sharing the body of the freebusy request you made? I am trying to figure out freebusy requests and so far have only been able to successfully make free-busy-query requests for my own calendar, but I would like to be able to retrieve the freebusy from other users. Below is the payload I am sending in my request:

<?xml version='1.0' encoding='utf-8'?>
<C:free-busy-query xmlns:C="urn:ietf:params:xml:ns:caldav" xmlns:D="DAV">
        <C:time-range start="20180711T140000Z" end="20180712T220000Z"/>
</C:free-busy-query>

The following response is what I get:

BEGIN:VCALENDAR
VERSION:2.0
PRODID:-//Example Corp.//CalDAV Client//EN
BEGIN:VFREEBUSY
UID:null
DTSTART:20180711T140000Z
DTEND:20180712T220000Z
DTSTAMP:20180713T191302Z
FREEBUSY;FBTYPE=BUSY:20180711T163000Z/PT30M,20180711T180000Z/PT1H,20180712
 T200000Z/PT30M
END:VFREEBUSY
END:VCALENDAR

How did you get the originator and attendee params to show up in the response?
