HttpResponseStream doesn't work when ending the stream without a write #97

export const handler = awslambda.streamifyResponse(
    async (event, responseStream, context) => {
        const metadata = {
            statusCode: 404,
            headers: { "Content-Type": "text/plain", "X-Foo": "Bar" }
        };
        responseStream = awslambda.HttpResponseStream.from(responseStream, metadata);
        // This will cause a 502 with no custom response headers:
        responseStream.end("Not Found");
        // This will cause a 200 with no custom response headers:
        responseStream.end();
    }
);
