heroku open を行うと以下のように表示されます
[vagrant@localhost memo]$ heroku open ▸ Error opening web browser. ▸ Error: Exited with code 3 ▸ ▸ Manually visit https://************* in your browser.

を見ながら対処をしたのですが、ページを表示しようとすると The page you were looking for doesn't exist.と表示されてページ自体が存在しない感じになってしまいます
文字数制限の関係であまり詳しく書けませんが、いったい何が原因なのでしょうか？デプロイした時の最後のほうに出てる警告3つに関しては対応したと思うのですが、heroku openをしたときのError: Exited with code 3とは何を指すのか、また、ページが表示されないのはこのエラーのせいなのかだけでも教えていただけないでしょうか
