pydantic UserWarning: Valid config keys have changed in V2

Question

I'm getting an error related to migrating the Pydantic version. Code made in v1, and pydantic installed in v2.

I try replace the class Config for the model_config, but i don't had success and the error continued the same. I tried too replace the field for de annotation, but i dont have success.

the codes where i do using pydantic:

config:

from pydantic import BaseConfig


class Settings(BaseConfig):
    DATABASE_URL: str
    MONGO_INITDB_DATABASE: str

    ACCESS_TOKEN_EXPIRES_IN: int
    REFRESH_TOKEN_EXPIRES_IN: int
    JWT_ALGORITHM: str

    CLIENT_ORIGIN: str

    JWT_PRIVATE_KEY: str
    JWT_PUBLIC_KEY: str

    class Config:
        env_file = "./env"


settings = Settings()

model (here i dont know how i could add the prop json_encoders in model config):

from typing import List, Annotated

from bson import ObjectId

    @classmethod
    def __get_validators__(cls):
        yield cls.validate

    @classmethod
    def validate(cls, v):
        try:
            return ObjectId(str(v))
        except Exception:
            raise ValueError("not a valid ObjectId")
