Exception thrown in tentatively_accept_invite()

[gregn610]

I've got a loop over what I think is a list of very similar invites but it's repeatably throwing an exception. This against a hosted Baïkal 0.9.1 server, I can provide access if that helps.

    for inbox_item in course.principal.schedule_inbox().get_items():
        # NB! No idea what I'm doing here !!!
        obj = CalendarObjectResource(client=course.ical_client, url=inbox_item[0])
        if obj.is_invite_request():
            print(f"tentatively accepting invite for {obj.icalendar_instance.subcomponents[0]['organizer']}")
            obj.tentatively_accept_invite(calendar=course.calendar)
            obj.delete()

Many thanks!

"Unsupported media type", that's weird.

The scheduling extension (send/accept invites) is not very well-tested, found it difficult to test the code as very few calendar servers supports the extensions fully, and since I will need three accounts on the same server to fully test it.

I can't tell anything about the time frame as I'm very busy over the next few days, but if you provide me with three test accounts on the server I can try to look into it when I get time.

I found one obvious bug in March that I fixed, but I still haven't been able to get the tests passing, and haven't had much capacity for looking into it. v0.9 is way overdue for release, so it will unfortunately be released without better support for the scheduling.

Sorry ... I've been prioritizing other things than scheduling lately ... but I will definitively get back to this one.
