I'm seeing this response based on copy/paste from the curl generated by the "generate code" on graph.cool:

```
HTTP/1.1 400 Bad Request
Content-Type: text/plain; charset=UTF-8
Content-Length: 135

The request content was malformed:
application/x-www-form-urlencoded (of class akka.http.scaladsl.model.ContentType$WithMissingCharset)
```

Is the curl request generally broken or is it possible it's something else (I'm using a valid bearer from the UI too)
