unicornの起動ができない Cannot load `Rails.config.active

前提・実現したいこと

現在、作成したオリジナルアプリをhttps://qiita.com/naoki_mochizuki/items/5a1757d222806cbe0cd1こちらの記事に従ってawsにデプロイしようとしています。
そこで、unicornが起動しません。
bundle exec unicorn_rails -c /var/www/rails/viewhome/config/unicorn.conf.rb -D -E production
を実行すると
master failed to start, check stderr log for detailsと表示されます。
logを見ると下記のエラーがでています。

INFO -- : Refreshing Gem list
bundler: failed to load command: unicorn_rails (/home/kei/.rbenv/versions/2.7.1/bin/unicorn_rails)
NoMethodError: Cannot load `Rails.config.active_storage.service`:
undefined method `match' for nil:NilClass

私はオリジナルアプリをrailstutorialを参考にしながら作成しました。
active_storageの設定も参考にしています。

$ heroku config:set AWS_ACCESS_KEY=<accessキー>
$ heroku config:set AWS_SECRET_KEY=<secretキー>
$ heroku config:set AWS_REGION=<リージョン名>
$ heroku config:set AWS_BUCKET=<bucket名>

を実行し、

config/storage.yml

test:
  service: Disk
  root: <%= Rails.root.join("tmp/storage") %>

local:
  service: Disk
  root: <%= Rails.root.join("storage") %>

amazon:
  service: S3
  access_key_id:     <%= ENV['AWS_ACCESS_KEY'] %>
  secret_access_key: <%= ENV['AWS_SECRET_KEY'] %>
  region:            <%= ENV['AWS_REGION'] %>
  bucket:            <%= ENV['AWS_BUCKET'] %>

config/environments/production.rb

  config.active_storage.service = :amazon

としています。
herokuでは問題なく動きます。
変更すべき点やしないといけない事等ありますでしょうか。
解決方法わかる方いましたら教えていただきたいです。
