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: meeting_notification_service.rb
    path of file: ./repos/openproject/modules/meeting/app/services
    
    the code of the file until where you have to start completion: class MeetingNotificationService
  attr_reader :meeting
    
  def send_notifications!(action, include_author:, **)
    author_mail = meeting.author.mail

    recipients_with_errors = []
    meeting.participants.includes(:user).find_each do |recipient|
      next if recipient.mail == author_mail && !include_author

      MeetingMailer.send(action, meeting, recipient.user, User.current, **).deliver_later
    rescue StandardError => e
      Rails.logger.error do
        "Failed to deliver #{action} notification to #{recipient.mail}: #{e.message}"
      end
      recipients_with_errors << recipient
    end

    recipients_with_errors
  end
