Webdriverio Selenium Standalone Service v6 onwards - unable to overwrite the hostname for private Selenium backend - webdriver-io

Question

Webdriverio Test Runner has an option
- if you are using a private Selenium backend, you should define the hostname, port, and path here.
hostname: 'localhost',
port: 4444,
path: '/',
Since version: "#wdio/selenium-standalone-service": "^6.0.0"
This "hostname" is unchangeable and always stay as localhost. It seems to autodetect that it should be localhost only and does not refer to config at all i.e. even if I update manually in wdio.conf.js as
hostname: 'selenium-hub',
port: 4445,
path: '/',
Upon execution, still the hostname stays 'localhost' instead of being 'selenium-hub' and port stays as '4444' instead of '4445'
In previous version the command line value with --hostname was getting overwritten successfully as required
i.e. ./node_modules/.bin/wdio wdio.conf.js --hostname 'selenium-hub'
would pass selenium-hub as hostname successfully....
anyone experiencing similar issue ?

Answer 1

add the hostname, port, and path to the capabilities array.
instead of:
hostname: '{ unique ip address}',
port: { port number },
path: {'/'},
protocol: '{http' || 'https'},
capabilities: [{
maxInstances: 5,
browserName: 'chrome',
}],
Do this:
capabilities: [{
maxInstances: 5,
browserName: 'chrome',
hostname: '{ unique ip address}',
port: { port number },
path: {'/'},
protocol: '{http' || 'https'},
}],
