rails sでbooting pumaというエラー

reila serverを立ち上げたいです

VScodeのターミナルでrails sを実行すると下記のようなエラーが出ます。
初歩的な質問で申し訳ないのですが、よければ教えてください

rails s
=> Booting Puma
=> Rails 6.0.0 application starting in development
=> Run rails server --help for more startup options
RAILS_ENV=development environment is not defined in config/webpacker.yml, falling back to production environment
Exiting

エラーは「コードの挿入」を使ってもらえると見やすくなります。この記事と同じ事象ではないですか？ https://qiita.com/jiko797torayo/items/4bfb65ffcb8a5de0de7a あとbooting pumaはエラーではなく、アプリケーションサーバのpumaを起動しますというログメッセージです。
