Obtenir TypErrror lors de l'appel stop_conversation()

Question

J'essaie d'étendre google assistant pour pouvoir utiliser mes propres commandes locales, cela fonctionne, mais la voix répond toujours avec "Je ne peux pas vous aider avec ça" ou quelque chose de similaire . Lorsque je tente d'utiliser la méthode stop_conversation() je reçois une erreur:

TypeError: unbound method stop_conversation() must be called with Assistant instance as first argument (got nothing instead)

Comment puis-je résoudre ce problème?

Voici un code que je moded pour mon projet assistant google et je suppose que c'est ce que vous recherchez. La fonction stop_conversation doit être appelée avec la fonction d'assistant, sinon elle va déborder les erreurs.
