I have the same problem with pydantic-core version 2.14.6 on Python 3.13. It does not happen on Python 3.11 or below. Did not test Python 3.12.

Log file with Python 3.13: https://github.com/zhmcclient/python-zhmcclient/actions/runs/11495456556/job/31995020656?pr=1685

Duplicate of #1366, please update.

[andy-maier]

The problem is this dependency (shown for Python 3.12):

$ python -m pipdeptree -p pydantic-core -r
pydantic_core==2.14.6
└── pydantic==2.5.3 [requires: pydantic_core==2.14.6]
    ├── safety==3.2.3 [requires: pydantic>=1.10.12]
    └── safety-schemas==0.0.7 [requires: pydantic~=2.5.0]
        └── safety==3.2.3 [requires: safety-schemas>=0.0.2]

But I agree that this is not the fault of pydantic or pydantic-core.

Just for the record, and for future readers, I have reported this to the safety repo as pyupio/safety#620, along with our circumvention.
