Heroku deployは成功するのですが、App crashedというErrorでアプリが開けないです(code=H10) (syntax error)

Herokuにデプロイ後、下記のエラーが発生します。

前提・したこと

ローカルでアプリ制作
Heroku CLIをインストール

terminal
1$ curl -OL https://cli-assets.heroku.com/heroku-linux-x64.tar.gz
2tar zxf heroku-linux-x64.tar.gz && rm -f heroku-linux-x64.tar.gz
3sudo mv heroku /usr/local
4echo 'PATH=/usr/local/heroku/bin:$PATH' >> $HOME/.bash_profile
5source $HOME/.bash_profile > /dev/null

rails_12factor　をGemに追加

Gem
1group :production do
2  gem 'rails_12factor'
3end

Git経由でアプリケーションを登録

$ git init
$ heroku create
$ heroku addons:add cleardb
$ heroku config | grep CLEARDB_DATABASE_URL
環境変数を変更

出力されたデータベース情報のmysqlの部分をmysql2に変更して、heroku config:setコマンドで設定を上書き
0. $ git add .
0. $ git commit -m "update for upload to heroku"
0. $ git push heroku master
0. こちらを参考にRails+CarrierWave+heroku環境でAWS S3へ画像をアップロードする処理を実行

処理後、更新するとApplication errorが発生。

「syantax error」と表示されていたので、関連してそうな周辺の文字列を検索すると
「カンマ抜け」ではないかと推測したのですが、場所が特定できませんでした。

試したこと・調べたこと

補足情報（FW/ツールのバージョンなど）

macOS Catalina 10.15.6
Rails 5.2.4.3
ruby 2.5.1p57 (2018-03-29 revision 63029) [x86_64-linux]
heroku/7.42.5 linux-x64 node-v12.16.2
AWS Cloud9

.
Cloud9上では問題なく起動します。DB、S3バケット内にもimageが反映されます。

問題、原因の特定に必要なファイルやコードがありましたら、ご指摘願います。

前者のログについてはよくわかりませんが

     2: from /app/vendor/bundle/ruby/2.5.0/gems/activestorage-5.2.4.3/lib/active_storage/engine.rb:95:in `block (2 levels) in <class:Engine>'

から

activestorage-5.2.4.3/lib/active_storage/engine.rb:95で問題が発生している事がわかるので
config/storage.ymlがERBとしてなにか破綻していることがわかります。

バグで文章がきえていたため修正

asm様、ご解答いただきありがとうございました。おっしゃる通り、config/storage.yml　が問題でした。 storage.ymlのamazonの箇所をコメントアウトを外していなかったことが原因でした。 amazon: service: S3 access_key_id: <%= ENV["AWS_ACCESS_KEY_ID"] %> secret_access_key: <%= ENV["AWS_SECRET_ACCESS_KEY"] %> region: ap-northeast-1 bucket: <%= ENV["AWS_BUCKET"] %> ログの見方が広がり、大変参考になりました。本当にありがとうございました。
