Is there a way to access session stored in redis in log configuration stage in rails?

I have a rails 7 web app, which uses redis, hiredis, redis-actionpack to store session data. We also use devise for auth. Now, I wish to use log tags to include user_id in every line the logger logs. Is there a way to do this without me having to call redis.get directly and Marshaling stuff out?

If we used cookie store - the default thing, shaking the cookie jar would work -

   # Prepend all log lines with the following tags.    config.log_tags = [:request_id, proc do |req|      session_key = Rails.application.config.session_options[:key]      session_data = req.cookie_jar.encrypted[session_key]      if session_data.present?        warden_data = session_data['warden.user.user.key']"user_id: #{warden_data[0][0]}" if warden_data.present?      end    end]

But I don't want to touch redis directly.
I have tried req.session.to_hash or req.session[:_csrf_token] etc to try and force it, but it doesn't stick. I always get an empty {} back, staring blankly!

How can I use any higher level function to access session data?
