title: Karate UI Initial Get Call to BrowserStack Failing
body: <p>I'm attempting to do a POC for our mobile browser automation testing using Karate UI and BrowserStack.  I noticed Karate attempts to make a GET call to BrowserStack when the test starts, and is receiving a 500:</p>
  
  <pre><code>GET https://user:key@hub-cloud.browserstack.com/wd/hub
  31 &gt; Accept-Encoding: gzip,deflate
  31 &gt; Connection: Keep-Alive
  31 &gt; Host: hub-cloud.browserstack.com
  31 &gt; User-Agent: Apache-HttpClient/4.5.11 (Java/11.0.7)
  
  12:18:18.140 [main] DEBUG com.intuit.karate - response time in milliseconds: 152.10
  31 &lt; 500
  31 &lt; Connection: keep-alive
  31 &lt; Content-Type: application/json; charset=utf-8
  31 &lt; Date: Tue, 21 Apr 2020 19:18:18 GMT
  31 &lt; Server: nginx
  31 &lt; Transfer-Encoding: chunked
  31 &lt; accept: application/json
  {"value":{"message":"Invalid Command"}}
  </code></pre>
  
  <p>As you can see running Java 11.  Also running Junit5.  Here's my setup so far(username and key have been replaced for security):</p>
  
  <pre><code>Background:
  
    * def session = {capabilities: {deviceName: 'iPhone X', platformName: 'iOS', browserName: 'safari'}, desiredCapabilities: {deviceName: 'iPhone X', platformName: 'iOS', browserName: 'safari'}}
    * configure driver = {type: 'chrome', webDriverSession: '#(session)', start: false, webDriverUrl: 'http://user:key@hub-cloud.browserstack.com/wd/hub'}
  </code></pre>
  
  <p>And the stacktrace from the Karate report.  Thinking it might be complaining about the <code>session</code> variable?  I followed the Karate setup, the browserstack setup, and the W3C webdriver docs.</p>
  
  <pre><code>org.opentest4j.AssertionFailedError: consumer.feature:13 - driver config / start failed: class net.minidev.json.JSONObject cannot be cast to class java.util.List (net.minidev.json.JSONObject is in unnamed module of loader 'app'; java.util.List is in module java.base of loader 'bootstrap'), options: {type=chrome, webDriverSession={capabilities={deviceName=iPhone X, platformName=iOS, browserName=safari}, desiredCapabilities={deviceName=iPhone X, platformName=iOS, browserName=safari}}, start=false, webDriverUrl=http://user:key@hub-cloud.browserstack.com/wd/hub, showDriverLog=true, target=null}

  <p>UPDATE:  Am able to run the basic Java test using the same Maven project, so likely the issue lies somewhere in Junit or Karate.
