Can't share to a local User

Hey, first sorry for my bad englisch ;).

Nextcloud version (eg, 10.0.2): 11.0.3
Operating system and version (eg, Ubuntu 16.04): Ubuntu 16.04
Apache or nginx version (eg, Apache 2.4.25): 2.4.18
PHP version (eg, 5.6): 7.0.15
Is this the first time you’ve seen this error?: It’s the first time

Can you reliably replicate it? (If so, please outline steps):

The issue you are facing:
I have a few users and I can share anything to a few of them, but if I search for a new user or group Nextcloud can’t find this user or the group. But the User / the Group exists!

The output of your Nextcloud log in Admin > Logging:
Undefined index: FN at /var/www/owncloud/current/apps/files_sharing/lib/Controller/ShareesAPIController.php#585

The output of your config.php file in /path/to/nextcloud (make sure you remove any identifiable information!):

The output of your Apache/nginx/system log in /var/log/____:
Same output like in the admin log. (Undifined Index, Variable not found, the Error is in the ShareesAPIController.php!

I have exactly the same issue. I cannot share anything with a few users. If i search the users cannot be found for sharing.

Bump !!! This is still an issue on 12

Same issue here.
This is the error message that I see when I am looking for the username “pa” in the Share textbox.

As a consequence, I cannot share anything with use “pab” that does exist.

OK, the behavior can be repaired by removing the email address attached to the account!!! I dont understand why… If anyone can offer some help…

The faulty behavior may have been introduced here:

Of interest, a freshly created user with an email address is not impacted by the faulty behavior.

To summarize,

  • after upgrade to NC 12, users created in the past with an email address are impacted by a bug (“invalid cloud id”) which prevents other users to share folders with them (it is even more insidious than that: the “invalid cloud id” bug prevents the suggestion menu from popping up…
  • this bug comes from a new code in this commit: ; the CLOUD value that the contacts manager finds is invalid (for example, for user pab, it is “pab@” which is then seen as invalid by resolveCloudId function
  • a new user created with an email address after NC 12 deployment does not raise any issue

I need help to understand where the contactsManager finds the CLOUD value (is there a field or something else in the database for this?) in this extract of code:

$addressBookContacts = $this->contactsManager->search($search, ['EMAIL', 'FN']);
foreach ($addressBookContacts as $contact) {
  if (isset($contact['isLocalSystemBook'])) {
	if ($exactEmailMatch) {
	    $cloud = $this->cloudIdManager->resolveCloudId($contact['CLOUD'][0]);

This bug was fixed here: see and

This post can be put as resolved.
