@ishaksebsib thanks for this! we are going to do a wholesale rewrite of the langchain docs this week. happy to still give you credit on the PR for finding this stuff! can we cut the code example entirely for now?

Hi @jeffchuber,

Thanks for the feedback. I've removed the code example as requested and updated the PR.

Let me know if there's anything else I can assist with. I'm also happy to help with the upcoming documentation rewrite if needed.
