My front code is this in nextjs

const createRecvTransport = async () => {
  socket.emit('createWebRtcTransport', { consumer: true }, async (params: WebRtcTransportParams) => {
    recvTransport = await device.createRecvTransport(params.params);
    recvTransport.on('connect', ({ dtlsParameters }, callback, errback) => {
      socket.emit('connectConsumerTransport', {
        transportId: recvTransport.id,
        dtlsParameters,
      });
      
      callback();
    
    });


    // After the transport is created, emit the consumeMedia event
    socket.emit('consumeMedia', { rtpCapabilities: device.rtpCapabilities }, (response) => {
        console.log('Consume media response:', response);
        // Handle the response here (e.g., set up video elements, etc.)
    });
    
  });
};

back end code is below

socket.on("createWebRtcTransport", async ({ consumer }, callback) => {
    
    console.log("listen createWebRtcTransport");

    const roomId = peers[socket.id].roomId;
    const router = rooms[roomId].router;
    console.log("createWebRtcTransport", roomId);

    createWebRtcTransport(router).then(
      (transport) => {
        callback({
          params: {
            id: transport.id,
            iceParameters: transport.iceParameters,
            iceCandidates: transport.iceCandidates,
            dtlsParameters: transport.dtlsParameters,
          },
        });

        // add transport to Peer's properties
        addTransport(transport, roomId, consumer);
      },
      (error) => {
        console.log(error);
      }
    );
  });

  const createWebRtcTransport = async (
    router: any
  ): Promise<WebRtcTransport> => {
    return new Promise(async (resolve, reject) => {
      try {
        const webRtcTransport_options = {
          listenIps: [
            {
             ip:'0.0.0.0',
             announcedIp:process.env.PUBLIC_IP,
            },
            // {
            //   ip: process.env.PUBLIC_IP, // replace with relevant IP address
            //   announcedIp: "127.0.0.1",
            // },
          ],
          enableUdp: true,
          enableTcp: true,
          preferUdp: true,
        };
        console.log("webRtcTransport_options", webRtcTransport_options);

        const transport: WebRtcTransport = await router.createWebRtcTransport(
          webRtcTransport_options
        );
        console.log(`transport id: ${transport.id}`);

        transport.on("dtlsstatechange", (dtlsState) => {
          if (dtlsState === "closed") {
            transport.close();
          }
        });

        transport.on("@close", () => {
          console.log("transport closed");
        });

        resolve(transport);
      } catch (error) {
        reject(error);
      }
    });
  };

RecvTransport.on('connect) does not trigger i don’t where i am doing mistake
