Initial Checks

  • I have searched GitHub for a duplicate issue and I'm sure this is something new
  • I have searched Google & StackOverflow for a solution and couldn't find anything
  • I have read and followed the docs and still think this is a bug
  • I am confident that the issue is with pydantic (not my code, or another library in the ecosystem like FastAPI or mypy)

Description

Using Pydantic 1.10.15 with Python 3.12.4 throws the following error:

TypeError: ForwardRef._evaluate() missing 1 required keyword-only argument: 'recursive_guard'

This looks very similar to this issue fixed recently in typeguard by this PR: agronholm/typeguard#460.

Example Code

I initially discovered the error when trying to import fastapi (it was failing here), but I was able to reproduce by defining a model containing a type which doesn't exist yet:

Python 3.12.4 (main, Jun  7 2024, 19:37:37) [GCC 10.2.1 20210110] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import pydantic
>>> class Foo(pydantic.BaseModel):
...     foo: "Nope"

Note: I don't reproduce with Pydantic 2. Too bad it happens right when I was working on the migration of my project 😅 .

Seeing the same issue. In our case we are using pydantic 2.7.1, but are importing mergepythonclient which relies on V1.

Seconded, this is an issue that specifically cropped up moving from python 3.12.3 to python 3.12.4. It also affects pydantic.v1 within pydantic==2.7.3

My solution was to downgrade python to version 3.12.3 and it worked properly
