https://developers.weixin.qq.com/minigame/dev/guide/open-ability/game-recorder.html startRecord(){     if(wx.getGameRecorder){       console.log("start record");       var recorder = wx.getGameRecorder();              recorder.on('start', () => {         // 真正开始录制后的 5 秒后结束录制         setTimeout(() => { console.log("stop record");        recorder.stop().catch(res =>{             console.log("stop error:");             console.log(res);             })         }, 5000)       })       recorder.on('stop', (res) => {         console.log('对局回放时长: ${res.duration}');         window.wxplatform.shareRecord();       })       recorder.on('error', res =>{         const error = res.error           console.log("recorder error:");           console.log(res);         })       recorder.start() .catch(res =>{     console.log("start error:");     console.log(res);     })     }       } 调用上面函数 startRecord()后就只有一句日志： start record 证明start()函数并没有真正执行，也没捕抓到任何错误。完全不知到如何入手解决这个问题。我的设备是红米note 8 pro, 基础库是2.19.2
