I’m following the tutorial here. The preflight request/response looks like this…
XMLHttpRequest cannot load https://api.twitter.com/oauth2/token. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost:4200' is therefore not allowed access. The response had HTTP status code 400.

For reference, the code that makes the request looks like this…
`import ENV from 'vapour/config/environment'`
`import Em from 'ember'`
options =
type: 'POST'
url: 'https://api.twitter.com/oauth2/token'
data: 'grant_type=client_credentials'
headers:
'Authorization': "Basic #{window.btoa "#{ENV.TWITTER_CONSUMER_KEY}:#{ENV.TWITTER_CONSUMER_SECRET}"}"
TwitterApplicationOnlyAuthenticationInitializer =
name: 'twitter-application-only-authentication'
initialize: ->
Em.$
.ajax options
.then (result) ->
console.log result
`export default TwitterApplicationOnlyAuthenticationInitializer`
Thanks
