Hi guys, it looks like renderToHTML returns a response, and therefore the example is broken because cachable-response also is trying to return the content (Error [ERR_HTTP_HEADERS_SENT]). Cannot set headers after they are sent to the client). I tried the canary release and I see the same problem. How I can make this example work?
