Answer 1

私は、スタックトレースを使用することは本当に難しいとDeinum氏は同意します。つまり、私は最近、spring-cloud-vault-starter-configを使用しようとしているときに同様の例外が発生しました。

金庫の設定（spring.cloud.vault.*）が不足していると思われる詳細は、src/main/resources/bootstrap.ymlである必要があります。

これは、vault-starter-configがspring-cloud-configに関連するプロジェクトであり、一般的なスプリングブートのロードが進む前に処理を実行する必要がある（Vaultから設定値を取得する）ためです。
