Description

Image Image

As shown in the image, when I use graph = builder.compile(checkpointer=memory), LangSmith doesn’t work — likely because of a conflict with the built-in Postgres db. Usually I experiment in Jupyter Notebook and later convert my notebooks to .py files using jupyter nbconvert. Because of this conflict, I have to manually edit the generated Python files each time to remove it, which feels cumbersome — especially since both LangGraph and LangSmith are part of the LangChain ecosystem.

If a workaround or official solution already exists, I’d really appreciate being pointed in the right direction. :)
