In this example, we didn't declare any Pydantic model. In fact, the request body is not even <dfn title="converted from some plain format, like bytes, into Python objects">parsed</dfn> as JSON, it is read directly as `bytes`, and the function `magic_data_reader()` would be in charge of parsing it in some way.

Nevertheless, we can declare the expected schema for the request body.

  /**
   * Peeks up to [byteCount] bytes from the response body and returns them as a new response
   * body. If fewer than [byteCount] bytes are in the response body, the full response body is
   * returned. If more than [byteCount] bytes are in the response body, the returned value
   * will be truncated to [byteCount] bytes.
   *
   * It is an error to call this method after the body has been consumed.

     *
     * @param buffer the buffer to read into
     * @param remoteAddress remote memory address
     * @param remoteKey remote access key
     * @param length number of bytes to read
     * @return number of bytes read
     * @throws IOException if operation fails
     */
