An error is caused and in 2 js files there is a note marked "TODO handle null errors" and this error occurs.

First here is the error when I launch for example my microphone or camera:

/home/debian/node/dcs/mediasoup/src/Peer.js:24
    let producer = await this.transports.get(producerTransportId).produce({
                                                                 ^

TypeError: Cannot read properties of undefined (reading 'produce')
    at Peer.createProducer (/home/debian/node/dcs/mediasoup/src/Peer.js:24:66)
    at Room.<anonymous> (/home/debian/node/dcs/mediasoup/src/Room.js:92:56)
    at new Promise (<anonymous>)
    at Room.produce (/home/debian/node/dcs/mediasoup/src/Room.js:90:12)
    at Socket.<anonymous> (/home/debian/node/dcs/mediasoup/src/app.js:175:58)
    at Socket.emit (node:events:513:28)
    at Socket.emitUntyped (/home/debian/node/dcs/mediasoup/node_modules/socket.io/dist/typed-events.js:69:22)
    at /home/debian/node/dcs/mediasoup/node_modules/socket.io/dist/socket.js:614:39
    at process.processTicksAndRejections (node:internal/process/task_queues:77:11)

Node.js v18.12.1

I think the error occurs with the 2 comments there are here whose note is "TODO":

• mediasoup-sfu-webrtc-video-rooms/src/app.js

  Line 179 in 6446c24

  //TODO null handling

• mediasoup-sfu-webrtc-video-rooms/src/Peer.js

  Line 23 in 6446c24

  //TODO handle null errors

Does anyone have an idea how to fix/make them?
