Ошибка: не удалось найти драйвер для AutomationName «Appium» и platformName «Android»

Когда я пытаюсь запустить свое приложение с помощью nodejs. Я получаю указанную выше ошибку на сервере appium

файл test.js

var wd = require("wd");
var appDriver = wd.remote({
    hostname: '127.0.0.1',
    port: 4723,
})

var config = {};

config.android19Hybrid = {
   automationName: 'Appium',
   browserName: '',
   platformName: 'Android',
   platformVersion: 19,// API level integer, or a version string like '4.4.2'
   autoWebview: true,
   deviceName: 'any value; Appium uses the first device from *adb devices*',
   app: "D:\\market-deliveryboy\\platforms\\android\\app\\build\\outputs\\apk\\debug\\app-debug.apk"
};

appDriver.init(config.android19Hybrid);

Ошибка, которую я получаю на сервере Appium

Я пытаюсь решить это, но не добиваюсь успеха. Я больше в тестировании Ionic + Appium. Если у вас есть какое-либо решение для этого, это очень полезно для меня.

заранее спасибо
