Tools & Routing

Hi Everyone

I am taking the Functions, Tools and Agents with LangChain course. I am now on the topic on Tools and Routing. When I run this code block:
spec = OpenAPISpec.from_text(text)
in my Jupyter Notebook running in VS Code, I get this error : AttributeError: ‘super’ object has no attribute ‘parse_obj’.

All the code blocks before the above code block execute properly without errors. What could the problem be? On the video content, the entire notebook runs without any errors.

Thanks for any help.

Regards
