Rendering

    def render_errors!(exception, errors = nil)
        errors = if errors.nil?
                     exception.errors
                 else
                     exception.message(errors)
                 end

        raise 'Unknown Error' unless errors.present?

        render json: errors.merge({ success: false }),
               status: errors[:status]
    end
