vdirsyncer fails to sync privately shared icloud calendars

[brabalan]

My partner privately shares two icloud calendars with my calendars. Both calendars fails to sync with the following backtrace:

error: Unknown error occured for icloud_cal/xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx: /xxxxxxxx/calendars/xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
/xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx.ics
debug:   File "/usr/lib/python3.7/site-packages/vdirsyncer/cli/tasks.py", line 69, in sync_collection

debug:   File "/usr/lib/python3.7/site-packages/vdirsyncer/storage/dav.py", line 505, in get_multi
debug:     raise exceptions.NotFoundError(href)

These calendars have an id that is much longer than the "normal" calendars (64 characters). Could this be a size limit on the file name?

• Your vdirsyncer version: 0.16.7
• If applicable, which server software (and which version) you're using: icloud calendars
• Your Python version: 3.7.3
• Your operating system: ArchLinux, up to date
• Your config file:

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

[pair icloud_cal] a = "icloud_cal_local" b = "icloud_cal_remote" collections = ["from a", "from b"] metadata = ["displayname"]

[storage icloud_cal_local] type = "filesystem" path = "~/.calendars/icloud/" fileext = ".ics"

[storage icloud_cal_remote] type = "caldav" url = "https://caldav.icloud.com/" username = "…" password = "…"

Exactly the same configuration, exactly the same error under MacOS.

• vdirsyncer version 0.16.7
• icloud calendars
• python:3.7.4
• os: Mac OS Catalina 10.15

I'm having the same issue at the moment with vdirsyncer 0.19.0. I can sync non-shared calendars from icloud but when I attempt to sync the shared one I get an internal server error. This is the error log.

This is my experience aswell, trying to sync to/from a shared icloud calendar..

Can you provide a full debug log? The error in 0.19.0 seems different from the error in 0.16.7.
