We're sorry, but something went wrong. の原因がわからない。

##　現状
awsにデプロイをしようとして2日間詰まっています。
インスタンスやvpcなどの設定は全て完了しており残すところ今のエラーを解決できればというところで詰まっています。

調べてみるとこのエラー分の原因は人によってまちまちであるということは理解できるのですが
ローカルで動くのななぜ本番では動かなくなるのかが全くわからないです。

おそらくどこかの記述が誤っているのだと思うのですが知見があさくどこか分かりません。

いえ、指摘されているのはそのviewではないです
下からふたつ目の FATALに
app/views/layouts/application.html.haml:10
とあります。
= javascript_pack_tag 'application'
が原因です。

webpack　を使うことになっていますが、それは意識的に？それともいつの間にかそうなってる？
webpackを使うつもりはなく、実際に使っていないなら、この行を削除ですが、
使っている可能性があるなら、
`

You want to set webpacker.yml value of compile to true for your environment
unless you are using the webpack -w or the webpack-dev-server.
webpack has not yet re-run to reflect updates.
You have misconfigured Webpacker's config/webpacker.yml file.
Your webpack configuration is not creating a manifest.

`
を行うことになります。config/webpacker.yml　あります？

なお、、
私はwebpackについてはわからないので、その設定に関する問題やproduction環境で行うべきことが問題となりましたら、識者にタッチです。

ありがとうございます。回答いただいてからwebpackの件色々調べてみましたがどれもうまくいきませんでした。 winterboumさんがおっしゃっているように = javascript_pack_tag 'application'のコメントアウトにて無事解決いたしました。本当にありがとうございます。
