Only Level 1 headings syncing even though IDs are assigned

[code-SL]

Syncing two-way is working well, but only for headlines at level 1. Is this expected behavior? I am only syncing DEADLINE marked entries, but these entries are at multiple levels some at level 1, 2, etc.

IDs are being assigned on the right entries (i.e. even non-level-1 headlines, which is expected behavior), but only level 1 headlines are actually being exported to the icalendar export (and thus being synced).

See below config.

(use-package org-caldav
  :straight (org-caldav :type git :host github :repo "dengste/org-caldav")
  :config
  (setq org-caldav-url "myurl.com/foo/bar")
  (setq org-caldav-calendar-id "orgmode")
  (setq org-caldav-inbox "baz.org")
  (setq org-caldav-debug-level 2)
  (setq org-caldav-files nil)
  (setq org-caldav-sync-todo t)
  (setq org-icalendar-include-todo 'all)
  (setq org-caldav-skip-conditions '(notdeadline))
  (setq org-caldav-save-directory "bazdirectory")
  (setq org-icalendar-timezone "America/New_York")
  (setq org-caldav-sync-on-save t)
  (setq org-caldav-delete-org-entries 'ask)
  )

I suspect skip conditions is the culprit: if any parent heading (on level 1 for instance) would be skipped according to skip conditions sub headings are also skipped when syncing, regardless of whether skip conditions apply to them and even though ID:s are correctly generated for them. At least that's what I make of the code. ID:s are generated by org-caldav-create-uid while the questionable logic described above is applied in org-caldav-skip-function. I personally "solved" this issue by overwriting org-caldav-skip-function with a dummy-function (that does nothing apart from sending a warning to the message buffer). Seems to work. Mind you, this breaks any functionality associated with org-caldav-days-in-past.

@r39ex would you share your override?
I'm interested in that because my Todo are structered:

• PROJECT
  ** NEXT
  

Because PROJECT has no timestamp there are sync errors, because the target calendar does not accept items without a date.
If I try to filter out these PROJECT items to underlying NEXT items don't get processed.

@chaapp87 Not much to share, I just override the function, effectively making it a NOP:

(defun org-caldav-skip-function (foo)
   (message "Skipping org-caldav-skip-function!"))

Obviously, it's not a good solution, but it works for me.
