        response_mapping_template: <p>The <code>Function</code> response mapping template.</p>
        function_version: <p>The <code>version</code> of the request mapping template. Currently, the supported value is 2018-05-29. Note that when using VTL and mapping templates, the <code>functionVersion</code> is required.</p>

        code: <p>The <code>function</code> code that contains the request and response functions. When code is used, the <code>runtime</code> is required. The <code>runtime</code> value must be <code>APPSYNC_JS</code>.</p>

    Raises:
