Merged PR 282: エラーの挙動について確認する

## 概要
[Task2302: エラーの挙動について確認する](https://paruru.nds-tyo.co.jp:8443/tfs/ReciproCollection/fa4924a4-d079-4fab-9fb5-a9a11eb205f0/_workitems/edit/2302)

- ローカル環境でのみ静的ファイルをホストするよう修正
- 不要なビルドが行われている箇所を修正

## レビューポイント
- develop/staging環境での動作に影響がなさそうか
- 該当ファイルを修正しただけで問題なくCI/CDも修正される認識だが合っているか

## 動作確認状況
- ローカルで確認
