Cakephp 3.0:查找查询返回空结果

是这样的:

$this->loadModel('IntAdmin');
$test = $this->IntAdmin->find('list', [
    'contain' => ['Sales', 'Accounts'],
    'conditions' => [
        'IntAdmin.status' => 'submitted',
        'IntAdmin.id IN' => [$picking_lists['picking_list']]
    ]
]);
pr($test);
exit;

在$picking_lists中，我有:

Array
(
    [picking_list] => Array
        (
            [0] => 10
            [1] => 11
        )
)

这是pr()结果:

我在这里找不到问题，但查询返回空结果。请帮助。
