Я хочу получить результаты для всех записей, но могу получить результат только для одной записи в Laravel 5.6

Question

Я получаю ошибку при сравнении event_id для всех записей из базы данных. Это работает для отдельной записи, но я хочу получить cast_crew из всех записей. Проверьте ниже на ошибку, выданную почтальоном. Пожалуйста, помогите мне.

  $input = json_decode(file_get_contents('php://input', true));
