SessionNotCreatedError: Request body does not contain required parameter 'capabilities'.

Steps to reproduce -

let wd = require('selenium-webdriver');
let safari = require('selenium-webdriver/safari');
let opts = new safari.Options();
opts.setTechnologyPreview(true);
let caps = opts.toCapabilities();
let driver = new wd.Builder().withCapabilities(caps).build(); 

so how could I contain capabilities in request body?

I just upgraded to Safari 12 and now all my Selenium / WebDriver tests are failing with the error.
SessionNotCreatedError: Request body does not contain required parameter 'capabilities'.

Which is peculiar because I have defined capabilities.

This issue happens because Safari 12 uses a new (W3C) webdriver protocol which appears incompatible with selenium-webdriver v3.6

safaridriver can be passed a --legacy flag to use the old protocol.

I got this working in my project with the following:

const webdriver = require('selenium-webdriver');
const safari = require('selenium-webdriver/safari');

new webdriver.Builder()
    .usingServer(await new safari.ServiceBuilder().addArguments('--legacy').build().start())
    .forBrowser('safari')
    .build();

More details in #6431

Edit: pinging @jleyba FYI it appears the latest stable version of the node package doesn't work by default with Safari 12 which is now generally available.

For me, it was choking on the 'await', but this works:

new webdriver.Builder()
    .usingServer( new safari.ServiceBuilder().addArguments('--legacy').build().start())
    .forBrowser('safari')
    .build();

using node v8.12.0
