• Construct and return the final response to API Gateway:

        def graphql(event, context):        http_method = event['httpMethod']        response = handle_graphql(http_method, event)        status_code = 200        response = {          'statusCode': status_code,          'body': json.dumps(response),          'headers': CORS_HEADERS,        }        return response
