Description
Initial Checks
- I confirm that I'm using Pydantic V2
Description
I'm hoping to incorporate some custom error handling using the :class:PydanticKnownError. I tried to use the example from the docs, but this raises a TypeError rather than the expected PydanticKnownError.
A potentially quick solution would be to mark the arguments as positional-only with / and updating the docs to reflect this, but this appears to be the opposite of most pydantic classes.
Example Code
# from the example docs -> https://docs.pydantic.dev/latest/api/pydantic_core/#pydantic_core.PydanticKnownError
from pydantic_core import PydanticKnownError
def custom_validator(v) -> None:
if v <= 10:
raise PydanticKnownError(error_type='greater_than', context={'gt': 10})
return v
