• I added a very descriptive title to this issue.
• I searched the LangChain documentation with the integrated search.
• I used the GitHub search to find a similar question and didn't find it.
• I am sure that this is a bug in LangChain rather than my code.
• The bug is not resolved by updating to the latest stable version of LangChain (or the specific integration package).

Example Code

from langchain.storage import LocalFileStore

Description

I had 0.1.16 version of langchain installed and this morning pulled up fresh docker to re-install my environment, found out a back compatibility issue.

Langchain depends on langchain_community, which a few days ago was using 0.0.34, now that it updated to 0.0.35. langchain's import of LocalFileStore would fail.

OS: Linux
Python: 3.11

Could you share the output of:

python -m langchain_core.sys_info

[eyurtsev]

We're re-releasing

I am also running into this issue:

Just downgraded my langchain_core to 0.1.46 from a few days ago and it seems to work again.

!pip install langchain_core=0.1.46

[eyurtsev]

Could you try with the following versions of community and core?

langchain-community==0.0.36
[langchain-core==0.1.48]https://github.com/langchain-ai/langchain/releases/tag/langchain-core%3D%3D0.1.48

[stawils]

i had same error during open-webui installation
(
from langchain_core.stores import InvalidKeyException
ImportError: cannot import name 'InvalidKeyException' from 'langchain_core.stores'

)

@eyurtsev , by adding:
langchain-community==0.0.36
langchain-core==0.1.48

it fixed the problem.
