ActiveRecord::RecordNotFound

Question

フリマアプリの購入機能を実装していますがデータを保存しようとコントローラーを設定したところCouldn't find Item without an IDと出てしまいました。原因が分かる方がいらっしゃいましたらご教授願います。

addresses_controller.rb

class AddressesController < ApplicationController

  def index
    @address = Address.new
    @item = Item.find(params[:id])
    @addresses = @item.addresses.includes(:user)
  end

  def create
    @address = @item.addresses.new(address_params)
    if @address.save
      redirect_to root_path
    else
      render :new
    end
  end

  private
   def address_params
    params.require(:address).permit(:post_number, :prefecture_id, :municipality, :address, :build_name, :phone_number).merge(user_id: current_user.id, item_id: params[:item_id])
   end
 
end

model/address

class Address < ApplicationRecord
  extend ActiveHash::Associations::ActiveRecordExtensions

  belongs_to :purchase
  belongs_to :prefecture

  with_options presence: true do
    validates :post_number, format: { with: /A\d{3}[-]\d{4}z/, message: 'Input correctly' }
    validates :municipality
    validates :prefecture_id, numericality: { other_than: 1, message: 'Select' }
    validates :address
    validates :phone_number, format: { with: /A\d{11}z/, message: 'Input only number' }
  end
end

試したこと
indexアクションに以下の記述を記載した。
@address = Address.new
@item = Item.find(params[:id])
@addresses = @item.addresses.includes(:user)
