Jenkinsエージェントはプログラム「docker」を実行できません：エラー= 2、そのようなファイルまたはディレクトリはありません

jenkinsエージェントで奇妙な動作をします。Dockerにアクセスできるマスターと個別のビルドエージェントがあります。

ビルドエージェントで次のパイプラインスクリプトを実行している間：

node {
    sh "id"
    sh "echo $PATH"
    sh "docker ps"
    docker.image("node:latest").inside("") {
        sh "npm --version"
    }
}

次の出力が得られます。

出力は、シェルとして実行している場合、dockerpsが正常に機能することを示しています。Dockerビルドステップで実行すると、特定の例外が発生します。

私が間違っていることについて何か考えはありますか？
