Unexpected exception on redis disconnect Redis - NoMethodError(undefined method `destroy' for nil:NilClass)

Commencez à la ligne 66 de ruby/hyper-operation/transport/connection_adapter/redis.rb, puis parcourez la chaîne d’appels de disconnect via connection.rb et action_cable.rb. Suivez pourquoi le chemin de déconnexion de Redis atteint destroy sur nil ; c’est terminé lorsque la déconnexion d’un channel ne lève plus le NoMethodError signalé.

I switched recently to the new Redis message functionality and I get the following exception in production.log

I had the same problem when using the db message store and back then i had to patch hyperstack.rb initializer with the following patch from @catmando :

module Hyperstack
  class Connection < ActiveRecord::Base
    def self.disconnect(channel)
      puts "\ndisconnecting from #{channel}\n" if Rails.env.development?
      c = find_by(channel: channel, session: nil)
      if c
        c.destroy
      else
        puts "\n********************** WARNING #{channel} has not been opened.  Why are we disconnecting ?????????? \n"
      end
    end
  end
end

Why is this happeing?
