Cannot integrate webdriver-io boilerplate project with Browserstack #18

Hi, I am trying to integrate Browserstack with https://github.com/webdriverio/appium-boilerplate/.
I have created new conf.js file

`exports.config = {
services: ['browserstack'],
user: process.env.BROWSERSTACK_USERNAME || 'xxxxxxxxxxxxxxxxxxxxxxxx',
key: process.env.BROWSERSTACK_ACCESS_KEY || '000000000000000000000',
browserstackLocal: true,
updateJob: false,
specs: [
'./tests/specs/app*.spec.js',
],
exclude: [],

capabilities: [{
    name: 'single_appium_test',
    build: 'webdriver-browserstack',
    device: 'Samsung Galaxy S7',
    browserName: 'android',
    app: process.env.BROWSERSTACK_APP_ID || 'bs://xxxxxxxxxxxxxxxxxxxxxxxxxxxx',
    appPackage: 'com.wdiodemoapp',
    appActivity: 'com.wdiodemoapp.MainActivity',
    'browserstack.debug': true
}],
logLevel: 'verbose',
coloredLogs: true,
screenshotPath: './errorShots/',
baseUrl: '',
waitforTimeout: 10000,
connectionRetryTimeout: 90000,
connectionRetryCount: 3,

framework: 'mocha',
mochaOpts: {
    ui: 'bdd',
    timeout: 20000
}

};
When I am running tests I am getting errors in console:> appium-boilerplate@5.0.0 android.browserstack C:\Source\appium-boilerplate-master

wdio ./config/wdio.android.browserstack.conf.js
