Ruby on RailsのWebアプリをRenderでデプロイしたい

実現したいこと

renderを使って、Ruby on Railsを用いたWebアプリを公開したいです。

前提

Ruby on Railsで作っているWebアプリをrenderを使ってデプロイしようとしているのですが、今の知識では太刀打ちできないエラーが出て必ずデプロイに失敗してしまいます。

1# 特定のモデルやコントローラーの特定の記述がおかしい、みたいな話ではない・・・かも？2# ただ、設定に関わるファイルがそもそも存在していない可能性や、依存性の問題が発生しているのだろうと思いました。

試したこと

ダメもとで、ターミナルの

"npm install"

コマンドで依存関係を一度まっさらに再インストールする、というやり方を試してみましたが、効果がありませんでした。
