Symfony version 2.8.33

Example problem:

->add('order', ChoiceType::class, [
    'expanded' => true,
    'choices' => [
        'view' => 'news.search.order.view',
        'name' => 'news.search.order.name',
        'date' => 'news.search.order.date',
    ],
    'empty_data' => 'date',
])

In this case, i get an error at this line:

Warning: date() expects parameter 1 to be string, object given
