Graphql variables in nested types

Got error while playing with graphql API in worldcup branch.

Error :
{
  "data": {
    "worldcups": null
  },
  "errors": [
    {
      "message": "Cannot read property 'replace' of undefined",
      "locations": [],
      "path": [

              "locations": [],
              "path": [
                "worldcups"
              ]
            }
          ],
          "stacktrace": [

            "    at new CombinedError (/home/nowuser/src/node_modules/graphql-tools/src/stitching/errors.ts:85:5)",

            "    at fulfilled (/home/nowuser/src/node_modules/graphql-tools/dist/stitching/delegateToSchema.js:4:58)"
          ]
        }
      }
    }
  ]
}

while running following query :

query Matches($year: Int!, $round: String) {
  worldcups(year: $year) {
    name 
    matches(round: $round) {
      round
      description
      homeScore
      awayScore
    }
  }
}

with variables :

{
  "year": 2018,
  "round": "Group matches - Group C"
}

Does it work with literals?

Yes, query with literals works.
