Thanks for noting @mdziezyc - seems like the guys at langchain have been refactoring their docs repo over the past few months and broke some internal links - You can easily locate the notebook here.

Would you care to PR the fix? (note at the end of the day this is an issue for the langchain repo)

Fixed :)
