Issue with current documentation:

This is for the documentation page: https://python.langchain.com/en/latest/modules/agents/agents/examples/structured_chat.html This does not work in Jupyter or if you download it to a .py file and run it. You do get 2 different errors though. When you run this in Jupyter you get this error:

---------------------------------------------------------------------------

      2 # sync_browser = None # create_sync_playwright_browser()

ConfigError: field "sync_browser" not yet prepared so type is still a ForwardRef, you might need to call PlayWrightBrowserToolkit.update_forward_refs().

When you run it as a .py file you get this error:

Idea or request for content:

I would like to have a working example that I could download and run on my Jupyter server or Colab and it work as-is.
