bug: KeyError: '*' with @field_validator('*')

[mmzeynalli]

Description of the bug

Cannot build docs if I have field_validator for all fields: '*'

To Reproduce

from pydantic import BaseModel, ValidationInfo
from pydantic_core import PydanticUndefined


class BaseRequestSchema(BaseModel):

    @field_validator('*', mode='before')
    @classmethod
    def set_if_none(cls, v: Any, info: ValidationInfo):
        """If `None` is set, return default value for that field"""
        if (
            info.field_name
            and not cls.model_fields[info.field_name].is_required()
            and cls.model_fields[info.field_name].get_default() is not PydanticUndefined
            and v is None
        ):
            return cls.model_fields[info.field_name].get_default()
