Producer AudioTrack and VideoTrack

I find the following solution from the mediasoup discourse group while I was searching solution to the same problem: either audio or video is sent to the consumer; I couldn’t send send both the video and audio to the consumer,
the solution doesn’t seem to work for my case;

try {

    media_stream = await getUserMedia(mediaInputSource);
    // console.log('media_stream :', media_stream)
    const track = media_stream.getVideoTracks()[0];

    const audioTrack = media_stream.getAudioTracks()[0];

    const params = { track };

    const params2 = { audioTrack };

    if (chk_Simulcast.checked) {
      params.encodings = [
        { maxBitrate: 100000 },
        { maxBitrate: 300000 },
        { maxBitrate: 900000 },
      ];
      params.codecOptions = {
        videoGoogleStartBitrate : 1000
      };
    }
    videoProducer = await transport.produce(params);
    audioProducer = await transport.produce(params2)

  } 
  catch (err) {

    publish_status.innerHTML = err;

  }

There is clear documentation about how to do that in the website.
