@defer and @stream not working for federated subgraphs

[aarne]

A fairly typical pattern for @stream and @defer seems to be not working? I'm not sure if this is a regression in the version I'm using or it a bug.

query {
  goToSubgraphAndExecute {
    fastField1
    ... on ResponseType @defer {
      slowField1
    }
    progress @stream {
      id
      status
    }
  }
}

While the query works as expected directly via gateway the result is all nulls, But no error also :(

---
{"data":{"goToSubgraphAndExecute":{"fastField1":null,"progress":null,"__typename":"ResponseType"}},"hasNext":true}
---
{"incremental":[{"data":{"slowField1":null,"__typename":"ResponseType"},"path":["goToSubgraphAndExecute"]}],"hasNext":false}
-----

directly the response looks like this

---
{"data":{"goToSubgraphAndExecute":{"fastField1":true,"progress":[]}},"hasNext":true}
---
{"incremental":[{"items":[{"id":"1","status":"ok"}],"path":["goToSubgraphAndExecute","progress",0]}],"hasNext":true}
---
{"incremental":[{"data":{"slowField1":{...},"path":["goToSubgraphAndExecute"]}],"hasNext":true}
---
{"hasNext":false}
