Herokuへのデブロイ

Ruby on Rails Herokuへのデブロイ

　Ruby on Rails で作成したアプリケーションをHerokuへデブロイしようとしているのですが、

$ git push heroku master

の実行後にheroku openするとAplication errorが出てしまいました。

heroku logsやrails consoleでエラーの確認をして、bundle installやbundle update、rails db:migrate等を試してみたのですが上手くいきません。

また、Gemfileの

group :development, :test do
gem 'sqlite3', '~> 1.4'

の'~> 1.4'の部分を現在のバージョンに書き換えてみたのですがそれも違うようで困っています。何かわかる方がいらっしゃいましたら、よろしくお願いいたします。
