METHOD:REQUEST prevents sync

[simonostendorf]

I am using vdirsyncer in docker (container 2.5.5) with vdirsyncer 0.19.3 and python 3.12.6.

My config file looks like this:

(I removed the configs for my other calendars and contacts because they are not relevant here, but they are included in the log)

# example from https://github.com/pimutils/vdirsyncer/blob/main/config.example
# modified for usecase to sync NextCloud <-> Mailcow (SOGo)

[general]
status_path = "~/.vdirsyncer/status/"

[pair calendar_personal]
a = "calendar_nextcloud_personal"
b = "calendar_mailcow_personal"

# see "vdirsyncer discover"
# config name, name on site a (nextcloud), name on site b (mailcow)
collections = [["pair_calendar_personal", "personal-1", "personal"]]

[storage calendar_nextcloud_personal]
type = "caldav"
url = "https://nextcloud.example/remote.php/dav/calendars/my-username/personal-1/"
username = "my-username"
password = "my-password"

[storage calendar_mailcow_personal]
type = "caldav"
url = "https://mailcow.example/SOGo/dav/my-username/Calendar/personal/"
username = "my-username"
password = "my-password"

The output of vdirsyncer -vdebug sync is:
