`RequestValidationError` is a sub-class of Pydantic's <a href="https://docs.pydantic.dev/latest/concepts/models/#error-handling" class="external-link" target="_blank">`ValidationError`</a>.

**FastAPI** uses it so that, if you use a Pydantic model in `response_model`, and your data has an error, you will see the error in your log.

        SMBUtil.writeInt4(0, buffer, 60);

        return buffer;
    }

     * Creates a larger buffer suitable for testing negotiate contexts.
     */

        // Copy basic structure
        byte[] basic = createBasicNegotiateResponseBuffer();

 * body.
 *
 * ### The response body can be consumed only once.
 *
 * This class may be used to stream very large responses. For example, it is possible to use this
 * class to read a response that is larger than the entire memory allocated to the current process.
 * It can even stream a response larger than the total storage on the current device, which is a
 * common requirement for video streaming applications.

FastAPIはこれをするために、Pydanticモデルの`.dict()`を<a href="https://docs.pydantic.dev/latest/concepts/serialization/#modeldict" class="external-link" target="_blank">その`exclude_unset`パラメータ</a>で使用しています。
