LINE Messaging APIを使って、LINEからSpotifyにログインしたいです（Eclipse + Node.js +
herokuを利用しています）

自分で書いたindex.js内のエラーは一つずつ潰してきたのですが、今回インストールしたパッケージしかコンソールに表示されず困っています。

どなたか直すべきところや疑わしいところをご指摘いただけますと大変嬉しです。  
よろしくお願いします。

node.js api eclipse https line
Node.js 403：エラーログに自分で編集したファイル以外しか出てこない時のエラーの原因
Messaging APIからステータスコード403で返っているので、LINEアカウントの設定に何かしら問題がありそうです。  
LINE@ ManagerかLINE Developersから再度確認してみてください。

参考: <https://developers.line.me/ja/docs/messaging-
api/reference/#anchor-006a70a2021e9f35c762d309e9bd5f4e8aa94355>

質問文中のコードを試してみましたが、想定通り返答できているように見えます。

(少なくとも2019年現在では、)デベロッパーコンソールの「セキュリティ設定」で設定を行っているIPアドレス以外からメッセージ送信しようとすると `403`
が返ってくるようですのでそちらの設定の問題の可能性があります。

いわゆるやってみた系記事では上記IPアドレス設定が必須であるように読めるものも散見されますが、[未設定でも動作する](https://twitter.com/line_dev/status/789333727860056064)(注:
昔はServer IP
Whitelistという設定項目名だったようです)ので、もし何か設定されているのであれば一旦全削除して動作確認してみるのも手かと思います。
