Overview

Requests whose response code is between 300 and 599 and contain an <Error></Error> in their body are wrapped in an Error::Response. This Error::Response contains an Error object which raises an exception that corresponds to the error in the response body. The exception object contains the ErrorResponse, so in all cases where a request happens, you can rescue ResponseError and have access to the ErrorResponse and its Error object which contains information about the ResponseError.

begin
  Bucket.create(..)
rescue ResponseError => exception
 exception.response
 # => <Error::Response>
 exception.response.error
 # => <Error>
end
