调研方向

首先,在启用 Deck 日历/任务集成的情况下重现该故障,并检查加载委派日历期间的 DAV 响应,查找缺失的应用生成的 app-generated--deck--board-105 节点。比较禁用集成时的行为;完成标准是现有 Deck 看板能够正确暴露,并且无法解析的 Deck 节点不再阻止无关委派日历的加载。

描述

bug
Steps to reproduce
  1. Enable Deck calendar/tasks integration for a user.
  2. The user owns active Deck boards.
  3. Configure calendar delegation between two Nextcloud users.
  4. Open/reload the Calendar app as the user who receives the delegated calendar.
  5. Calendar fails to load the delegated calendars.
  6. DAV debugging shows an error for a Deck-generated calendar node, for example:
    Sabre\DAV\Exception\NotFound
    Node with name 'app-generated--deck--board-105' could not be found
    The referenced Deck board exists and is neither deleted nor archived.
  7. Disable Deck calendar/tasks integration for the affected user.
  8. Reload the Calendar app.

The delegated calendars now load correctly.

The issue is reproducible: enabling the Deck calendar integration causes the problem again; disabling it immediately resolves it.

Expected behavior

Deck calendar integration should not interfere with Calendar delegation.

Existing Deck boards should be correctly exposed as app-generated CalDAV calendar nodes. If a Deck-generated calendar node cannot be resolved, this should not prevent unrelated delegated calendars from being loaded.

Calendar delegation should work regardless of whether Deck calendar/tasks integration is enabled.

Actual behavior

With Deck calendar/tasks integration enabled, Calendar delegation fails and the Calendar app displays:

Delegated calendars could not be loaded.
Make sure the server supports calendar delegation.

The server does support calendar delegation. The delegation itself is correctly stored in oc_dav_cal_proxy, and normal CalDAV requests work.

During the failing request, SabreDAV reports:

<d:error xmlns:d="DAV:" xmlns:s="http://sabredav.org/ns">
<s:exception>Sabre\DAV\Exception\NotFound</s:exception>
<s:message>Node with name 'app-generated--deck--board-105' could not be found</s:message>
</d:error>

The referenced Deck board exists in oc_deck_boards, is active, and is not deleted or archived.

Other Deck-generated calendar nodes for the same environment can be accessed successfully.

As soon as Deck calendar/tasks integration is disabled for the affected user, calendar delegation works immediately. Re-enabling the integration reproduces the issue.
