Filter blocked after a request

Hi, I followed the getting started https://www.getenvoy.io/tutorials/getting-started-http-filter-rust/

then I changed the filter, just to try the response, but after the first request the filter gets blocked

 if let Err(err) = &filter_ops.send_response(403,
                                                   &[("form", "envoy filter")],
                                                   Some(b"Access forbidden.\n")) {

            info!("error {}", &err);

        }
        info!("******* request sent");

        Ok(http::FilterHeadersStatus::StopIteration)

The first request works:

< HTTP/1.1 403 Forbidden

< content-type: text/plain                                                                                                                                                                                                           
< form: envoy filter

< server: envoy  

Then it doesn't work anymore.

Thank you for the sdk
