Question

我写了这段代码：

getVideoDevices() { 
    return new Promise((resolve, reject) => { 
           ConnectyCube.videochat.getMediaDevices('videoinput').then(devices => { 
           devices ? resolve(devices) : reject(); 
          }); 
    });
 }

但是我在控制台中遇到此错误：

TypeError: undefined is not an object (evaluating 'b.enumerateDevices')

所有许可，例如摄像头和麦克风设置
