Mavros: 〜set_stream_rateサービス呼び出しへの応答がありません

問題の詳細

〜set_stream_rateサービス呼び出しを使用してIMUの更新レートを上げようとしています。 レートの増減も試みましたが、残念ながら成功しませんでした。

私は以下を試しました：
ターミナルの場合： rosservice call /mavros/set_stream_rate 1 200 1 （0 200 1、0 10 1、0 10 0などでも試してみました）

C ++の場合：

#include <mavros_msgs/StreamRate.h>

    ros::ServiceClient stream_rate_client;
    ros::NodeHandle nh;
    stream_rate_client = nh.serviceClient<mavros_msgs::StreamRate>("/mavros/set_stream_rate");

    mavros_msgs::StreamRate streamRate;
    streamRate.request.stream_id = 1;
    streamRate.request.message_rate = 200;
    streamRate.request.on_off = true;
    stream_rate_client.call(streamRate);

これらはどれも機能しませんでした。理由はわかりません。 また、デバッグの進め方もわかりません。
