Nice and easy! Can you add a task for yourself to test that the results look good before release?

Yeah, checked it with some queries.
Before the change:

$ curl localhost:8082/query -XPOST -d '{
  me(_xid_: alice-in-wonderland) {
author{name}
  }
}'
{"me":[{"author":[{"name":"aswewesd"},{"name":"Lewis Carroll"}]}]}

After:

$ curl localhost:8082/query -XPOST -d '{
  me(_xid_: alice-in-wonderland) {              
author{name}
  }
}'
{"me":{"author":[{"name":"aswewesd"},{"name":"Lewis Carroll"}]}}
