You can use Pydantic's model configuration to `forbid` any `extra` fields:

{* ../../docs_src/cookie_param_models/tutorial002_an_py310.py hl[10] *}

If a client tries to send some **extra cookies**, they will receive an **error** response.

            assertEquals(error, echoResponse.getException());
        }
    }

        statusField.setInt(smb, status);
    }
