      [`blueprint refactor-error-messages <https://blueprints.launchpad.net/horizon/+spec/refactor-error-messages>`_]
      User can see detailed error message on the horizon UI.
      This blueprint adds a hyperlink "details" in the alert box.
      So now when an exception occurs a user can click on this hyperlink
      "details" which shows original error message included in a corresponding
      error. This may help a user to understand what happens in detail.
