ios上的agora rtc未处理错误PlatformException（2，无效参数，null，null）

Question

我在 ios 上使用 agora rtc 时遇到未处理错误PlatformException(2, invalid argument, null, null) 错误，它在 android 上运行没有任何错误，下面是我的代码

   final RtcEngine _engine = await RtcEngine.create(AGORA_RTC_APP_ID);
   await _engine .enableVideo();
   await _engine .enableAudio();
   await _engine .setChannelProfile(ChannelProfile.LiveBroadcasting);
   await _engine .setClientRole(ClientRole.Broadcaster);
   await _engine .muteLocalAudioStream(true);
   await _engine .enableWebSdkInteroperability(true);
   final configuration = VideoEncoderConfiguration();
   configuration.dimensions = VideoDimensions();
   await _engine .setVideoEncoderConfiguration(configuration);
   await _engine .joinChannel(
          token,
          channelName,
          null,
          userId,
        );

Answer 1

问题是我没有传递 VideoDimensions 参数

configuration.dimensions = VideoDimensions(width: 1920, height: 1080);
