无法使用twilio视频访问参与者曲目

Question

我试图使用twilio视频api实施2人视频通话。我似乎无法访问任何参与者的音频/视频音轨，无论是在房间还是通过参与者连接的回拨。有问题的代码，我尝试访问新加入的参与者的曲目是：

Twilio.Video.connect(token, {name:room_name}).then(function(room) { 
    console.log('Successfully joined a Room:'); 
    //console.log(room); 
    room.on('participantConnected', function(participant) { 
    console.log('A remote Participant connected:'); 
    console.log(participant.sid); 
    participant.tracks.forEach(track => { 
     //This does not get added and the console.log doesn't fire. 
     console.log('adding track'); 
     document.getElementById('videoRow').appendChild(track.attach()); 
    }); 
    }); 
}); 

感谢您的帮助！
