SQLSTATE[23000]: Integrity constraint violation: 1062 Duplicate entry when trying to attach new permissions

• Laratrust Version: 6.3

When i try to update permissions for a specific user (it's an App\Models\Organization infact), i'm getting the following error:

SQLSTATE[23000]: Integrity constraint violation: 1062 Duplicate entry '1-8-App\Models\Organization' for key 'permission_admin.PRIMARY' (SQL: insert into permission_admin (admin_id, permission_id, user_type) values (1, 8, App\Models\Organization))

The code that does that looks like the following:

$organization = Organization::withTrashed()->find($organization_id);
$organization->syncPermissions($data["permissions"]);

Where $data["permissions"] contains IDs of permissions to add.

Strangely, the operation succeeds and the permissions are persisted, but the above error shows regardless.

I've did another try, i've detached the permissions and then re-attached them again, but the same error keeps on showing.
