Jsonファイルを読み込む場合、下記エラーとなりました。
異なるドメインからの呼び出しは制限されているようです。

Access to XMLHttpRequest at 'https://noteitemlist.netlify.com/nonItemList.json' from origin 'null' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource.

なので、VuejsとJsonファイルのサーバーを同じ場所に置いたら、ちゃんと動きました。
