HarmonyOS ArkTS不支持any数据类型做返回

public void onRoomStateUpdate(String roomID, ZegoRoomState state, int errorCode, JSONObject extendedData) {
  super.onRoomStateUpdate(roomID, state, errorCode, extendedData);
  ZegoLog.log("[onRoomStateUpdate] roomID: %s, state: %s, errorCode: %d", roomID, state.name(), errorCode);

  if (guardSink()) { return; }

  HashMap<String, Object> map = new HashMap<>();

  map.put("method", "onRoomStateUpdate");
  map.put("roomID", roomID);
  map.put("state", state.value());
  map.put("errorCode", errorCode);
  map.put("extendedData", extendedData.toString());

  sink.success(map);
}
