git push herokuが通らなくなってしまいました。

Question

前提・実現したいこと

heroku上でpostgresqlを使ったrailsアプリを実装したい

railsアプリを現在作成中です。当初postgresをdbに採用しproduction環境でheroku実装していました。途中で練習のためにmysql環境に変更しようとしたところ、エラー多発し、postgresqlに戻そうとしたがgit push herokuが通らなくなってしまいました。

発生している問題・エラーメッセージ

このようなエラーがでます。

$ git push heroku

どんな些細な情報でも構いません。ご指摘いただけると幸いです。

試したこと

上記ログのエラーメッセージに記載されている
gemfile.lockを削除してもう一度bundle install --without productionし直す.

remote:   NoMethodError: undefined method `deep_symbolize_keys' for #<String:0x0000558fb3325648>

この部分が怪しいと思ったのですが過去の記事を参考に色々といじってみたのですが改善せずです。。

補足情報（FW/ツールのバージョンなど）

ここにより詳細な情報を記載してください。

Answer 1

/config/environment.rb でハッシュを期待している位置に文字列を渡しています

参考: Rake aborted - NoMethodError: undefined methor 'deep_symbolize_keys'

you're probably passing a string in a line of your /config/environment.rb somewhere
where it's expecting a hash

ありがとうございます。secrets.ymlのfileの中に文字列が含まれていることが原因でした。
