If you want to -customize the body by adding other fields, you will need to make a different copy of the <code>RequestMessage</code> or completely -change the body to contain a different data type.

After each <code>RequestInterceptor</code> is run, the request is updated with the data from the final <code>HttpRequest</code> and -that is sent to the endpoint. There is a default interceptor added to every <code>Cluster</code> called "serializer". This -interceptor is responsible for serializing the request body is which what the server normally expects.

These -interceptors can be passed into either a <code>DriverRemoteConnection</code> or a <code>Client</code> using the interceptors parameter. An -interceptor is a <code>Callable</code> that accepts one argument which is the HTTP request (dictionary containing header, payload -and auth) or a list/tuple of these functions. The interceptors will run after the request serializer has run but before -any auth functions run so the HTTP request may still get modified after your interceptors are run. In situations where -you don’t want the payload to be serialized, the <code>message_serializer</code> has been split into a <code>request_serializer</code> and a -<code>response_serializer</code>. Simply set the <code>request_serializer</code> to <code>None</code> and this will prevent the <code>RequestMessage</code> from -being serialized. Again, this is expected to be an advanced feature so some knowledge of implementation details will be -required to make this work. For example, you’ll need to know what payload formats are accepted by <code>aiohttp</code> for the -request to be sent.</p> -</div> -</div> -<div class="sect3"> -<h4 id="_changes_to_deserialization_for_gremlin_javascript">Changes to deserialization for gremlin-javascript</h4> -<div class="paragraph"> -<p>Starting from this version, <code>gremlin-javascript</code> will deserialize <code>Set</code> data into a ECMAScript 2015 Set.
