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: conan_token.rb
    path of file: ./repos/gitlabhq/lib/gitlab
    
    the code of the file until where you have to start completion: # frozen_string_literal: true

# The Conan client uses a JWT for authenticating with remotes.
# This class encodes and decodes a user's personal access token or
# CI_JOB_TOKE
    
      def decode(jwt)
        payload = JSONWebToken::HMACToken.decode(jwt, secret).first

        new(access_token_id: payload['access_token'], user_id: payload['user_id'])
      rescue JWT::DecodeError, JWT::ExpiredSignature, JWT::ImmatureSignature
        # we return on expired and errored tokens because the Conan client
        # will request a new token automatically.
      end
