How can I test a NestJS WebSocket Server with Insomnia? Error: "socket hang up"

I'm trying to test my WebSocket Server. I want to connect to the server and verify If I can log an access token in the terminal. The Insomnia:

enter image description here

My Nest implementation:

@WebSocketGateway(0, {
  cors: {
    origin: '*',
  },
})
export class WorkGateway {
  @WebSocketServer()
  private server: Server;
  private logger: Logger = new Logger('WorkSocket');

  constructor(private readonly authService: AuthService) {}

  handleConnection(client: Socket) {
    const id = this.authService.verify({
      accessToken: client.handshake.headers.authorization,
    });

    console.log(id);
  }
}

From the React client, I'm able to connect, but not from Insomnia.

There is no support for socket io on Insomnia at current time. Go for Postman which support it since 2021.

Insomnia does not support Socket.io connection directly, only WebSocket. I tried to find a solution to the problem, how to test complex websocket connections with multiple event subscriptions, but it seems that so far only a simple connection can be configured, which is probably the solution for you. Try using - ws://localhost:3333/socket.io/?EIO=4&transport=websocket

Instead of - ws://localhost:3333/

Also try changing the configuration to

@WebSocketGateway({ cors: { origin: '*', }, transports: ['websocket'], })
