当我尝试遵循this aws real time streaming example的示例时
为什么我得到以下错误

/usr/local/include/aws/transcribestreaming/model/AudioStream.h:47:36: error: calling 'Jsonize' with incomplete return type 'Aws::Utils::Json::JsonValue'
       msg.WriteEventPayload(value.Jsonize().View().WriteCompact());
                             ~~~~~~^~~~~~~~~

我真的不知道为什么会发生这种情况，因为我只是按照所给的例子，这个问题发生，即使我只有

#include <aws/transcribestreaming/model/AudioStream.h>
