The source of this bug is that the pytest configuration for pytest-jupyter regards warnings as errors, and ipykernel has the following line in /usr/lib/python3/dist-packages/ipykernel/jsonutil.py (line 29): datetime.strptime("1", "%d") This raises a DeprecationWarning in Python 3.13. In the current GitHub, this line is replaced by: datetime.strptime("2000-01-01", "%Y-%m-%d") This change should fix this bug. Thanks, Julian
