User <$userId> not found.

Error message

User <$userId> not found.

What it means

InvalidArgumentException thrown by occ dav:import-calendar (apps/dav/lib/Command/ImportCalendar.php:80) when the first argument uid does not exist in the user backend (IUserManager::userExists() returns false). The command validates the target user before looking up the calendar.

Solutions

1. occ user:list to confirm the exact uid
2. Fix/reconnect the user backend if the user should exist, then re-run
3. Re-run the import with a valid uid

Example fix

# before
occ dav:import-calendar alic personal calendar.ics
# after
occ dav:import-calendar alice personal calendar.ics

if (!$userManager->userExists($uid)) {
    throw new RuntimeException("Unknown user $uid");
}

try { /* import */ }
catch (\InvalidArgumentException $e) {
    if (str_contains($e->getMessage(), 'not found')) { /* fix uid, re-run */ }
}

When it happens

Trigger: occ dav:import-calendar <uid> <uri> <location> with a non-existent uid: typo, deleted user, or user from an LDAP backend that is currently not resolvable.

Common situations: Import scripts replayed after users were removed; provisioning order mistakes (import before user import); LDAP server down during a batch import.
