次のことを無視してください：stackoverflowのは説明するエラーメッセージよりも多くの言葉を必要とし状況。エラーメッセージはどんな言葉よりも優れています！

問題を解決するための提案はありますか？ありがとう。

Answer 1

someone who had a similar problemによると、あなたはconfig/application.rbに行くと交換する必要があります。

config.middleware.insert_after('ActionDispatch::Static', '::API::Throttle') 

この行を代わりには：

config.middleware.insert_before('Rack::Lock', '::API::Throttle') 

は、この情報がお役に立てば幸い！

Answer 2

ミドルウェアスタックの前面に挿入する別のミドルウェアを指定する必要はありません。代わりに、インデックス番号だけを指定することができます。例：

config.middleware.insert_before(0, ::API::Throttle)
