Found a related issue - langchain-ai/langchain#5113

[joein]

Great thread, thanks

Seems like the issue is related to a recent typing_extensions update

pip3 install typing_extensions==4.5.0 fixes the issue for me

[joein]

@gaurav274 we will set typing-extensions = ">=4.0.0,<4.6.0" in the upcoming release
