This is a bug, not a usage question. For questions, please use GitHub Discussions.
I added a clear and detailed title that summarizes the issue.
I read what a minimal reproducible example is (https://stackoverflow.com/help/minimal-reproducible-example).
I included a self-contained, minimal example that demonstrates the issue INCLUDING all the relevant imports. The code run AS IS to reproduce the issue.

Example Code

from langgraph.graph import MessagesState
from prisma.models import Document

class CustomState(MessagesState):
    document_store: dict[str, str]

Description

Verified happening on langgraph 0.2.53 ~ 0.2.60

The problem is in graph/message.py, line 2.
There might be more instances throughout the code though, let's try to catch them all.

There were similar issues in the past:
https://github.com/langchain-ai/langgraph/issues/1856
https://github.com/langchain-ai/langgraph/issues/2198

Might be worthwhile to come up with a way to check that this remains compatible.

I might be able to issue a PR for this myself over the coming days.

Originally created by @mariomeissner on GitHub (Dec 31, 2024). ### Checked other resources - [X] This is a bug, not a usage question. For questions, please use GitHub Discussions. - [X] I added a clear and detailed title that summarizes the issue. - [X] I read what a minimal reproducible example is (https://stackoverflow.com/help/minimal-reproducible-example). - [X] I included a self-contained, minimal example that demonstrates the issue INCLUDING all the relevant imports. The code run AS IS to reproduce the issue. ### Example Code ```python from langgraph.graph import MessagesState from prisma.models import Document class CustomState(MessagesState): document_store:

There's a way to detect this with ruff too:

https://docs.astral.sh/ruff/rules/banned-api/

Might be useful to add.
