Wanted to drop a friendly note here.

Setting up the backend, I was running into this issue:

ImportError: cannot import name '_get_base_run_id_as_str' from 'langserve.server' (/opt/opengpts/backend/.venv/lib/python3.11/site-packages/langserve/server.py)

python: 3.11.7
pip: 23.3.1

I noticed the issue came from the requirements:
langserve>=0.0.23

Which was installing
langserve 0.0.36

I checked the Docker build (which was working) and the langserve version was 0.0.32

Of course, the issue has to do with the new change in langserve, but for other folks out there the quick fix is to change the requirements.txt to hardcode the langserve version:
langserve==0.0.32

can You please give more explanation on how to fix this issue? because I keep running into it even after I changed the requirements.txt to hardcode the langserve version:
langserve==0.0.32

Here is my requirements.txt that is working for me:

langchain-cli
-e packages/gizmo-agent
-e packages/agent-executor
langchain>=0.0.331
langserve==0.0.32
langsmith==0.0.70
permchain
python-multipart

I also hard set langsmith==0.0.70 (and python version 3.11.7)

Let me know if that works for you
