Reproduction repository for nest.js #4968

This repository contains a new nestjs app (nest 7.4.1) created using nest new-command.

It contains two gateways, one listening at the express-server's port (3000) another one at (3030). The chosen WebSocket-Adapter is ws, which is configured as descibed in the docs

Connecting to the server (i.e. 3000) and upgrading the connection fails due to the bug described in #4968. Connecting to the 3030 (which has a dedicated WS-server) works properly.

$ npm install

Start the server: npm run start:debug And in another terminal run: node socket-test.js

The last command runs a script which just tries to connect to both gateways. The seccond connection (to 3000) will crash the server.
