Answer 1

エラーがAWS領域がゼロである暗示するようです。

Aws.config.update({ 
    region: 'us-west-2', 
    credentials: Aws::Credentials.new('REPLACE_WITH_ACCESS_KEY_ID', 'REPLACE_WITH_SECRET_ACCESS_KEY'), 
    }) 

もしそうなら、あなたはあなたのDynamoid.configureコールとAws.config.updateのコードを投稿することができます。たとえば

https://github.com/Dynamoid/Dynamoid

：あなたはここにドキュメントごとにAWSライブラリを設定しましたコール。
