Capistorano デプロイ SSHKit::Runner::ExecuteError : rake exit status: 1の原因をご教授お願い致します

現在、railsをAWSでデプロイを試みておりますが、capistoranoのエラーで、
数日間困っております。
アプリ内ではactive storageを使用しており、S3を指定しております。
各キーは/etc/environmentに入れております。
また、AWSのキーはcredentialsにも念のため入れてます。

試みたこと
スワップ領域を用意しメモリの容量拡大
各種キーをenvironmentに保管（DATABASE_PASSWOR,SECRET_KEY_BASE,IAMキー）

情けないですが原因が全く分からないため、
お力添えの程、何卒宜しくお願い致します。

念のため、公開しても問題ない範囲で config/deploy/環境名.rb も掲載しておきましょう。（EC2や鍵のパスワードが特定されないように注意）エラーとしては bundle exec rake assets:precompile が失敗しているようです。また、precompileのエラーを起こしたときに私は config/environments/環境名.rb も修正した記憶があるので、そちらも掲載しておきましょう。ちなみにそのときは、javascript / css のシンタックスエラーもprecompile失敗の原因の一つだったので、javascript css をすべて見直すという苦行が発生しました... --- 確かなんの参考にもならなかったと記憶していますが念のため、 Refer to log/capistrano.log for details. とあるので、このファイルは軽く見ておきましょう（たぶん、コンソールログに表示されているものと全く同じ内容だった気がします...）

siruku6様、お力添えの程、ありがとうございます。それぞれのファイルを追記致しました。追記したエラーログに関してですが、有益な情報はないと判断して省いていたのですがどうでしょうか？また、config/environments/production.rbに書いている config.assets.compile = falseはtrueにしてみましたが、エラーは変わりませんでした。なお、以前ローカル内でRAILS_ENV=production rails assets:precompileとしたところ、 Compilation failed: ModuleNotFoundError: Module not found: Error: Can't resolve '@fortawesome/fontawesome-free' in '/Users/xxx/personal_app/xxxapp/app/javascript/packs' となり、失敗しました。未熟で申し訳ございませんが、何卒ご教授頂ければ嬉しい限りです。

遅くなって申し訳ないです。やはりcapistranoが出してくれたエラーログは大して役に立たなさそうです。ただし、なぜかcapistranoでprecompileしたときは出してくれないのですが、そうでないときはきちんとerror原因を出してくれているみたいですね。 ModuleNotFoundError: Module not found: Error: Can't resolve '@fortawesome/fontawesome-free' in '/Users/xxx/personal_app/xxxapp/app/javascript/packs' が原因のようです。 Can't resolve '@fortawesome/fontawesome-free' とあるので、これを解釈することができていないようです。 uglifierというgemの処理中に発生していると考えられるので、その辺を調べる必要があると思います。 --- ちなみに、uglifierは、productionモードで precompile するときだけ処理を行っており、処理内容としては、アプリにアクセスしてきた人が css や javascript を解読できないように、ソースを醜く(ugly)書き換えてくれる、というものになります。
