THEN Replace deprecated `class Config` with `model_config = ConfigDict(...)` in Pydantic models. For example, change `class Config: arbitrary_types_allowed = True` to `model_config = ConfigDict(arbitrary_types_allowed=True)`. This resolves the deprecation warning and ensures compatibility with Pydantic V3.

Instead of:
class MyModel(BaseModel):
    class Config:
        arbitrary_types_allowed = True

Use:
class MyModel(BaseModel):
    model_config = ConfigDict(arbitrary_types_allowed=True)
