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

{* ../../docs_src/cookie_param_models/tutorial002_an_py39.py hl[10] *}

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

                    styleField.setAccessible(true);
                    styleField.set(this, "test_style");

                    java.lang.reflect.Field transportContextField = NetworkExplorer.class.getDeclaredField("transportContext");

        String message = "forced downgrade detected";

        // Act
        SMBProtocolDowngradeException ex = new SMBProtocolDowngradeException(message, cause);

        // Assert - fields preserved
        assertSame(cause, ex.getCause());
        assertEquals(message, ex.getMessage());

        // Since message is explicitly provided, constructor should not need to call methods on cause
