AttributeError при использовании LangChain Google GenerativeAI в среде CrewAI ⇐ Python

[Anonymous]

Я столкнулся с ошибкой AttributeError при попытке использовать LangChain Google GenerativeAI в среде CrewAI. Ошибка возникает при выполнении метода Kickoff() экземпляра Crew. Конкретное сообщение об ошибке указывает на модуль langchain_google_genai, в котором упоминается ошибка AttributeError, связанная с отсутствием атрибута «_system_instruction» в объекте GenerativeModel.

И вот какая ошибка у меня возникла: -
