  Callback to be invoked upon a failed request.
  +.. describe:: allowDuplicates
  +
  + By default, Raven.js attempts to suppress duplicate captured errors and messages that occur back-to-back. Such events are often triggered by rogue code (e.g. from a `setInterval` callback in a browser extension), are not actionable, and eat up your event quota.

  + To disable this behavior (for example, when testing), set ``allowDuplicates: true`` during configuration.

  .. describe:: allowSecretKey
  By default, Raven.js will throw an error if configured with a Sentry DSN that contains a secret key.
