Unable to create config with submodel named "api"

[voodoo11]

When attempting to create a config with a submodel named "api", an error occurs:

pydantic_settings.sources.SettingsError: error parsing value for field "api" from source "EnvSettingsSource"

How to reproduce:

from pydantic import BaseModel
from pydantic_settings import BaseSettings

class ApiConfig(BaseModel):
    foo: str

class Config(BaseSettings):
    api: ApiConfig = ApiConfig()

Config()

Changing submodel name fixes the problem.

@voodoo11 Sorry for the late response. sub model name shouldn't make any problem. probably there is an env variable with the name api in your environment.

Thanks @hramezani.
