A clearer `ValidationError` should be provided with `Optional` settings about pydantic-settings HOT 2 CLOSED

Thanks @Andrew-S-Rosen for reporting this.

This is not related to pydantic-settings. the error message comes from pydantic.
BTW, I am unsure whether we should mention None here because it is the same for other errors e.g. invalid string.

from typing import Optional

from pydantic import BaseModel


class Settings(BaseModel):
    sample: Optional[str]

Settings(sample=2)
"""
pydantic_core._pydantic_core.ValidationError: 1 validation error for Settings
sample
  Input should be a valid string [type=string_type, input_value=2, input_type=int]
    For further information visit https://errors.pydantic.dev/2.6/v/string_type
"""

As you can see it says Input should be a valid string and does not mention None.

BTW, I closed the issue here and you can create a new issue on pydantic If this answer does not convinced you.

Thanks, @hramezani! You're totally correct. Apologies for that. I will report upstream.
