S3で画像を保存したいのですが、->getClientOriginalName()を使うと画像を読み込まなくなる

現在s3にファイルを保存することはできたのですが、できれば->getClientOriginalName()を使って名前を指定して保存したいと考えてます。
ですがメソッドを使うとファイル名 doesnt existと出ます。
公式から$contents = Storage::get('file.jpg');を見つけてここから呼び出すのかとパスを合わせても同様のエラーとなりました。
fileはpublic内に保存されてるのは確認済みです。

controller


public function store(Request $request, Book $book, Tag $tag)
    {
        $user = auth()->user();
        $data = $request->all();
        $file_name = $request->file('book_image')->getClientOriginalName();
        $request->file('book_image')->storeAs('/public/book_image',$file_name);

        $book_image = Storage::disk('s3')->putFile('book_image', $file_name, 'public');

        $data["book_image"]  = Storage::disk('s3')->url($book_image);

        $validator = Validator::make($data,[
            'title' => ['string', 'max:30'],
            'author' => ['string', 'max:30'],
        ]);
        $validator->validate();

        $book->bookStore($data);


        return redirect('/books')->with('success', '投稿が完了しました。');
    }

一応　config/filesystems.phpですが直す必要はないと思ってます。

どなたか知見のある方ご教授をよろしくお願いします。
