何度読み取らせてもステータス500が返るので、ログを仕込んだところ、ちゃんとバーコードを読み取れていました。 が、その後の、Amazonから返却されたXMLを変換するところで下記のエラーが発生していました。

※ログ中のXMLは、私が埋め込んだログなので、リポジトリ上のソースでは出力されません。

エラー発生箇所はItemLookup.scalaの47行目の「if (!I.isValid(res).text.toBoolean) {」ですが、resが空になっているようです。

ファイル選択でバーコード画像を読み取らせたところ、ちゃんと書籍情報が返ってきました！ ありがとうございます。 次はPCのカメラで試してみますー
