老师，在调用新版音乐播放时下面的代码怎么暂停不了音乐播放，
我打断点调试每次走了暂停，并且参数也变成了false，但之后不知怎么又变会了true

 //新版音乐播放
    const backgroundAudioManager = wx.getBackgroundAudioManager();
    backgroundAudioManager.title = postMusicData.title;
    backgroundAudioManager.epname = postMusicData.title;
    backgroundAudioManager.singer = postMusicData.title.substring(postMusicData.title.indexOf('-') + 1);
    backgroundAudioManager.coverImgUrl = postMusicData.coverImg;
     
    if (isPlayingMusic) {
      backgroundAudioManager.pause();

      this.setData({
        isPlayingMusic: false
      })
    } else {
      if (!backgroundAudioManager.src) {
        backgroundAudioManager.src = postMusicData.url;
      } else {
        backgroundAudioManager.play();
      }
      
      this.setData({
        isPlayingMusic: true
      })
    }

但手机端运行效果是正常的，但却报了一个这样的错
