createMediaRecorder 传入 type 是 webgl2 的 OffscreenCanvas 对象后报错 Error: Cannot get webgl context from target.

一物一码功能已开通：但是调用二维码申请时，返回报错？？ https://api.weixin.qq.com/intp/marketcode/tickettocode?access_token access_token用的是公众号appid和secret "errcode": 40097, "errmsg": "invalid args, openid invalid... hint: [VWU9NA08444007][2023-07-07 14:54:04] rid: 64a7b68c-35099cbf-617a4d80" [图片]

const options: XrFrame.IShareRecordOptions = { fps: 30, width: scene.width, height: scene.height, videoBitsPerSecond: 1000 }; // 启动录制 await scene.share.recordStart(options);  // 停止录制，直接保存到相册 await scene.share.recordFinishToAlbum(options); 保存到相册的视频，中间丢帧丢的厉害

在调用CameraContext.stopRecord时，无sucess或fail回调。视频录制时长大约在2分半-3分钟内。(mate 40, iphone 14 pro 等)个别机型特别频繁。 另外，IOS经常报 "errMsg":"operateCamera:fail operate fail" android 经常报："errMsg":"operateCamera:fail:is not recording"

请教一下，公司的小程序需要嵌入网页（资源挺大）到webview组件，嵌入的网页单独在微信浏览器打开，是没问题的，但是嵌入到webview组件以后，就会出现闪退，是因为webview和微信网页的调度资源机制不一致吗？烦请给个回复，谢谢
