missing required keys: [:id]の解決方法が分からない

Question

前提・実現したいこと

rails6 でSNSを製作中、いいね機能をajaxで非同期で実装しようとしています。
いいねのフォームはbook（投稿）のshowページにあるのですが、いいねをすでにしている状態でbookのshowページに戻ると、すでにしてあるいいねのidを見つけられずに、以下のエラーが出てしまいます。

発生している問題・エラーメッセージ

ActionView::Template::Error (No route matches {:action=>"destroy", :book_id=>"301", :controller=>"likes", :id=>nil}, missing required keys: [:id]):
    1: <%= form_with(url: book_like_path(@book, @like), html: { method: :delete }, remote: true) do |f| %>
    2:   <%= f.submit "いいねを取り消す", class: "btn" %>
    3: <% end %>

booksコントローラ

  def show 
    @book     = Book.find(params[:id])
    @like     = Like.new
    @comments = @book.comments
    @comment  = Comment.new
  end 

@like = Like.find_by(book: @book, user: current_user) || Like.new

なのかと思いましたmm
（すでにある場合に Like を取得できてないので
