Error: Timeout at ProxyStream._handleError

[elribonazo]

Hello!

I'm really surprised with this marvelous peace of code, must say... I'm working on something weird that does not have any sense haha and i'm getting a weird issue.

The backend (hyperswarm) sends a hello message to the customer (hyperswarm-web) after they connect, I do this with the hyperswarm package as follows:

  const sw = Swarm();
  sw.on('connection', (connection, _info) => {
    try {
      connection.setKeepAlive(600);
    } catch (exception) {
      console.log('exception', exception);
    }
    const response = new Readable();
    response._read = () => {};
    response.push('Something weird');
    response.push(null);
    response.pipe(connection);
  });
  sw.join(
    id,
    {
      announce: true,
      lookup: true,
    },
    () => {
      console.log(`Listening on ws://${domain}:${port}`);
      console.log(`-> Proxy available on ws://${domain}:${port}/proxy`);
      console.log(`-> Signal available on ws://${domain}:${port}/signal`);
      server.listen(port);
    }
  );

The client side implementation is using the hyperswarm-web as I said and I only listen for connections and do the join.
I initialize swarm only by passing the "bootstrap" attribute, nothing else.

Is this because I'm not encoding the message before sending with SwarmEncode? I have no idea and help would be much appreciated!

Would you be able provide a minimal repo which demos this error? It's a bit hard to know just from this snippet.

I think you'll need to periodically send packets down the connection regardless of the setKeepalive flag since I'm not sure if that's actually respected in web browsers.
