Laravel - Call to a member function hashName() on null?

Question

PHP

When adding a record to the database, it is not possible to save the selected file from the form and get a link for writing to the database, what could be the problem?

route:

Route::post('/post', '[email protected]')->name('store');

controller

public function store(Request $request)
    {
$post = new Post();
        $post->title = $request->title;
        $post->short_title = Str::length($request->title)>30 ? Str::substr($request->title, 0, 30) . '...' : $request->title;
        $post->descr = $request->descr;
        $post->author_id = rand(1,4);
            $path = Storage::putFile('public', $request->file('img'));
              $url = Storage::url($path);
              $post->img = $url;
             $post->save();
            return redirect()->route('home');
}

The form:

<form method="post" action="{{ route('store') }}">
    @csrf
    <div class="form-group"><input class="form-control" name="title" type="text"></div>
    <div class="form-group"><textarea class="form-control" name="descr" type="text"></textarea></div>
    <div class="form-group">
      <input class="form-control" name="img" type="file">
    </div>
    <input type="submit" value="Создать пост" class="btn btn-primary" name="" id="">
  </form>

Gives the following error:

Symfony\Component\Debug\Exception\FatalThrowableError
Call to a member function hashName() on null
