Node.js & Webdriver.io with Selenium Standalone Server can´t use custom profiles

Hey I downloaded geckodriver and included it with

java -Dwebdriver.firefox.driver="C:\\xampp\\htdocs\\project\\geckodriver.exe" -jar selenium-server.jar

I use Selenium Standalone Server 3.4.0

then in my node script I use

const options = {
desiredCapabilities: {
browserName: 'firefox',
firefox_profile:"C:/Users/Administrator/AppData/Local/Mozilla/Firefox/Profiles/greerg.profile"
}
} 
const client = webdriverio.remote(options).init();

It seems that it worked when I look into Selenium logs. Because there will be not created a temp profile at windows temp folders like in a new session instead you can see the profile from above. But it doesn´t worked. I doesn´t save cookies or addons or anything it´s like a fresh version every time. I also tried to use instead of firefox_profile, profile or "moz:profile" or I tried to import the profile as base64 string with fs. But nothing really worked maybe I just write it wrong? How can I include a custom profile - what code do you use?
