ローカルではエラーが出ずheroku上でActionView::Template::Error (ActiveStorage::FileNotFoundError):エラーが発生

Q&A

RubyJavaScriptRailsMySQLHeroku

解決したいこと

画像投稿ができるアプリケーションを開発しており、
現在、heroku上で「Failed to load resource: the server responded with a status of 500 (Internal Server Error)」エラーが発生しており解決出来ずにおります。
このエラーについてheroku上のデータベースをリセットして起動すると問題なく動作することができます。
ユーザー登録、投稿、投稿の編集、削除など一連の挙動を確認することが可能ですが、一定時間が経ってからブラウザを立ち上げると上記のエラーが発生してしまいます。
また、ローカル環境では問題なく挙動確認をすることもできエラーは発生しません。

以上です。

ご教授頂けると幸いです。

自分で試したこと

Active Storageに問題があると考えgemの確認、モデル内のアソシエーションやバリデーションの確認を行ないました。
gemについては
gem 'mini_magick'
gem 'image_processing', '~> 1.2'
を導入、bundle install済み。

sweet.rb
has_one_attached :image
validates :image, presence: true, unless: :was_attached?

def image_content_type
    extension = ['image/png', 'image/jpg', 'image/jpeg']
  end

def was_attached?
    self.image.attached?
  end
