TypeError: Cannot read properties of undefined (reading 'slice'). @nestjs/platform-socket.io

Question

Doesn't work if install all modules, but works if I install only

@nestjs/platform-socket.io: "9.1.6" and @nestjs/websockets: "9.1.6".

What am I doing wrong?

/node_modules/@nestjs/platform-socket.io/node_modules/engine.io/build/server.js:474
        const listeners = server.listeners("request").slice(0);
                                                     ^

Answer 1

npm i --save @nestjs/websockets @nestjs/platform-socket.io

Answer 2

@WebSocketGateway(80,{ cors: true, transports:['websocket'] })
@Injectable()
export class SocketService implements OnGatewayConnection, OnGatewayDisconnect {
  @WebSocketServer()
  server: Server;

  async handleConnection(socket) {
    console.info(`socket Connected ${socket}`);
  }
  async handleDisconnect(socket) {
    console.info(`socket Disconnected ${socket}`);
  }
}
