'GenericRelatedObjectManager' object is not iterable #19051
Description
Describe the bug
LDAP sync tasks fail with the above exception. Everything actually synchronises correctly, because Outgoing sync trigger mode is set to Deferred, and then the outgoing tasks fails last.
How to reproduce
- Trigger a source sync (LDAP in my case, but afaik this should impact all)
- Wait - user, group, and membership tasks succeed
- Outgoing fails, attempts retry
Expected behavior
Outgoing tasks start syncing.
Screenshots
No response
Additional context
I believe this could be a regression in #17669, specifically authentik/lib/sync/outgoing/models.py#L87. The ObjectManager is missing an all() call.
