Hello,
Can we put something like this? The problem I see is when the user does not exist in the escalade_users table.

if (
     $config->fields['use_filter_assign_group']
    && isset($user_config->fields['bypass_filter_assign_group'])
    && !$user_config->fields['bypass_filter_assign_group']
) {
    $condition['id'] = $groups_id_filtered;
}

-- edit
I hadn't seen Corentin's commit, but I agree with him.
If the configuration field were missing, the problem would be different in my opinion, but the existence of the user configuration is not checked, so new users might not have it.
