I get error 500 EofException when I try to query free-busy report. Tested on empty and non-empty calendars, and with events in the time-range or not.

The errors is due to the default timezone for the calendar being an empty string. Switching to UTC if this is the case solves the issue. I have not yet looked into why the timezone is empty.

Subject: [PATCH 1/1] freeBusyQueryReport uses UTC if default timezone for the
 calendar is the empty string instead of return 500 because VObject\Reader
 tries to read it

@lbeziaud I had that already figured out but wouldn't use it because all the events will be in UTC timezone because the test will skip to the else block.

Hi guys,

I've got the same error as above mentioned, even though I'm using UTC on client (thunderbird 60.8.0 lightning 6.2.8) and server side (baikal 0.53 on debian stretch, apache, sqlite). I already did a clean install of thundbird/lightning without any local contacts (only those via carddav from baikal) and only one caldav account (mine). When creating a new schedule in lightning the following error pops up in console (the following is the raw message, I just search/replaced names and mail adresses)

Maybe I'am just not able to setup lightning correctly, I doubt that I misconfigured baikal as one has not that much options here. If that's so I would be happy if someone could point me the right direction.

I have an issue with my Mas OS Calendar client described in #780 and have analysed it in more detail. In my case it's exactly the same problem as described by @chdaatson in his previous post: The server returns an 3.7;No calendar-home-set property found error for the POST request to the outbox, that is sent by the client.

But I think the problem is different from the one that was originally reported by @lbeziaud here. So I'm not sure if it is suitable to open a new issue.

Has anybody an idea, why the server returns 3.7;No calendar-home-set property found?
