I am using Mangum in a Lambda handler behind an API Gateway with a custom domain name. When I instantiate Mangum I provide my base path mapping with the api_gateway_base_path parameter. Inside my handler I reference the Request.url property, but it does not provide the actual URL used for the request because it does not include the API Gateway base path value in the path.
Reading the FastAPI docs it seems that this is what the root_path scope property is supposed to be used for, but in the APIGateway handler class root_path gets set to "".

Would it make sense for the
root_pathto be set to theapi_gateway_base_pathvalue if it is provided?
