Javascript Fetch not getting a response
<p>I'm invoking an authentication service via javascript fetch to get an access token.  The service is a simple RESTful call.  I can see the call is successful using fiddler (with a 200 response and json data).  However the fetch response never seems to get invoked.  Below is a snippet:</p>

<pre><code>const AUTHBODY = `grant_type=password&amp;username=${username}&amp;password=${password}&amp;scope=roles offline_access profile`
const AUTHHEADER = new Headers({'Content-Type': 'application/x-www-form-urlencoded'})

const CONFIG = {
    method: 'POST',
    headers: AUTHHEADER,
    body: AUTHBODY
}

fetch('http://localhost:23461/connect/token', CONFIG).then(function(response) {
    console.log('response = ' + response)
    return response.json()
}).then(function(json) {
    console.log('json data = ' + json)
    return json
}).catch(function(error) {
    console.log('error = ' + error)
})
</code></pre>

<p>When executing the fetch above none of the console.logs gets executed... seems to just hang.  But fiddler tells otherwise.  Any ideas?</p>
