git cloneからheroku openにかけてのエラーについて

課題でgithubにある既存のリポジトリを
git clone -b main app名
でクローンしました。

heroku createでherokuにデプロイして
gemfileを少し修正をした後、heroku openしました。
しかし下記のようなエラーが出ました。

Application error
An error occurred in the application and your page could not be served. If you are the application owner, check your logs for details. You can do this from the Heroku CLI with the command
heroku logs --tail

heroku logs --tailをターミナルで実行すると下記のようなログが流れました。
Build failed -- check your build output: に続くurlにあるエラーを解決しようと

https://qiita.com/sakashi/items/6b345fd558802c77083c
の記事を参考に修正をしましたが同じエラーログになります。

エラーの詳細を確認しようと
heroku run consoleをしても
irb(main):001:0>
と出てくるだけでどうしたらいいかわかりません。

git cloneできないような設定になっているとかありますか。
