You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: audience_validator.rb
    path of file: ./repos/vets-api/app/controllers/concerns/sign_in
    
    the code of the file until where you have to start completion: # frozen_string_literal: true

module SignIn
  module AudienceValidator
    
    
    def validate_audience!
      valid_audience = self.class.valid_audience

      return if valid_audience.blank?
      return if access_token.audience.any? { |aud| valid_audience.include?(aud) }

      Rails.logger.error('[SignIn::AudienceValidator] Invalid audience',
                         { invalid_audience: access_token.audience, valid_audience: })
      raise Errors::InvalidAudienceError.new(message: 'Invalid audience')
    end
