webSocketStartup logs "theWsServer.listen is not a function" — redundant .listen() call after constructor already starts the server

Abre appserver.js y localiza webSocketStartup; lee la construcción de websocket.Server y las llamadas de startup que aparecen a continuación. Elimina la llamada redundante a listen y verifica después que el startup ya no registre el mensaje not-a-function y que las conexiones WebSocket sigan funcionando.

When installing a test instance of rss.chat, Claude Code flagged an websockets error that turned out to not be an error. Here is Claude's bug report.

In appserver.js v0.8.3, the webSocketStartup function (rewritten 5/25/25) calls theWsServer.listen() after constructing the server with a port option:

theWsServer = new websocket.Server({port: config.websocketPort}); //5/25/25 by DW
theWsServer.on ("connection", handleWebSocketConnection);         //5/25/25 by DW
console.log ("webSocketStartup: config.websocketPort == " + config.websocketPort);
theWsServer.listen (config.websocketPort);   // ← throws

ws.Server has never exposed a public .listen() method. When you pass port to the constructor, the library creates an internal net.Server and calls .listen() on it automatically — the socket is already bound and ready before that last line runs. The call throws, the catch logs "webSocketStartup: err.message == theWsServer.listen is not a function", and the function returns.

The server is not broken — port binding and the connection handler are both set up before the throw, so WebSocket connections work normally. But the logged message looks like a fatal startup failure and will alarm anyone reading the logs.

Fix: remove the redundant .listen() call.

function webSocketStartup () {
    if (config.flWebsocketEnabled) {
        try {
            theWsServer = new websocket.Server({port: config.websocketPort});
            theWsServer.on ("connection", handleWebSocketConnection);
            console.log ("webSocketStartup: listening on port " + config.websocketPort);
            }
        catch (err) {
            console.log ("webSocketStartup: err.message == " + err.message);
            }
