GW fails for non custom schema

[wtrocki]

listen: localhost:8080
upstreams:
  note:
    type: graphql
    url: http://127.0.0.1:4000/graphql
types:
  - name: Query
    actions:
    - type: mount
      upstream: note
      query: query {}

This happens with the latest release and master.

So I have done some investigations and it looks like GW is not working with latest changes to graphql spec.

directive @cacheControl(maxAge:Int, scope:CacheControlScope) on 
"Exposes a URL that specifies the behaviour of this scalar."
directive @specifiedBy(  
  "The URL that specifies the behaviour of this scalar."
  url:String!
) on

that are included into the schema crashing gw.

Workaround is to get schema locally. Remove directives and use --production mode.
Amazing features @chirino. Really like how we can merge multiple serverless functions into single schema

Could you post the schemas that are giving you issues?

• we removed the parts mentioned above and all works so no worries. I might look into this issue in free time to see if we can ignore directives.

Hey, I'd like to work on this issue.
What would be a good starting point for the same?

[wtrocki]

This actually requires updating graphql library we use to official one. #41

[namit-chandwani]

Okay.
In that case, can I start working on issue #41 now?
