Webdriver cannot connect to Selenium server - selenium

Question

I am currently trying to set up webdriver and selenium together to run my automation tests through docker but am facing issues. Each time i try to run the tests I get the following error ERROR wdio-runner: Error: connect ECONNREFUSED 127.0.0.1:4444
I am using the selenium/standalone-chrome from docker and can see that the server is configured correctly and running at 127.0.0.1:4444 as I can hit it.
When I try to run webdriver however I seem to face the issue mentioned above. I believe the issue must be something in my webdriver config but having followed the documentation I can't see what's wrong...
const chai = require('chai');
const chaiWebdriver = require('chai-webdriverio').default;
const debug = process.env.DEBUG;
