Мой PDF-файл приложения Laravel 7 отлично работал на локальном хосте, но на интернет-сервере он выдает мне эту ошибку — gt; Эта страница не работает и в настоящее время не может обработать этот запрос. ОШИБКА HTTP 500. Каждый раз, когда я загружаю его обратно на локальный сервер, он все равно будет работать, как всегда, и продолжал выдавать мне те же ошибки на интернет-сервере. пожалуйста, как я могу это решить?
