【Rails】wicked_pdf Heroku で表示されない

Question

前提・実現したいこと

wicked_pdf を使用して、PDFを出力したいが、Heroku で４０４が返ってきて、PDFが出力されません。
ローカルでは表示できます。

Heroku でも同じように出力したいです。

Answer 1

コントローラーの記述が誤っていました。
以下のように修正

def show
  @resume = Resume.where(user_devise_id: current_user_devise.id)
  @user_devise_id
  
  @resume.each do |ele|
    @user_devise_id = ele.user_devise_id
  end

  @user_devise = UserDevise.find(@user_devise_id)

  respond_to do |format|
    format.html
     format.pdf do
       render pdf: 'filename',   # PDF名
              template: 'resumes/show.html.erb', # viewを対象にする
              orientation: 'Landscape', #　　横向き
              page_size: 'A4' # ページサイズ
              
     end
   end
 end
