Why does the file upload successfully but Laravel considers it an error?

Question

Laravel

Good day.
There is a simple file upload code. Everything works, but Lara says that "The file "exclude.jpg" was not uploaded due to an unknown error", although this is nonsense and absurdity, because the file is present at the destination. There is a physical movement of downloaded files.

// Сперва берем файл из реквеста, перемещаем его во временную директорию
// Все работает, но ошибка
$filePath = $file->move(
    storage_path('temp'),
    $file->getBasename() . '.' . $file->getClientOriginalExtension()
);

Why? How to fix? Obviously, this is a bug in the Symphony component (which is no wonder, if you look at how it is written). How to get around?
