Unknown directive \"@defer\ and @stream

[koo27]

Describe the bug

I'm trying to use the two directives @defer and @stream with no luck.
I set up a simple grapqhl yoga server, but the response I get from graphiQL is always "Unknown directive".
Here is a response example

{
  "data": null,
  "errors": [
    {
      "message": "Unknown directive \"@defer\".",
      "locations": [
        {
          "line": 5,
          "column": 17
        }
      ],
      "extensions": {}
    },
    {
      "message": "Unknown directive \"@stream\".",
      "locations": [
        {
          "line": 8,
          "column": 13
        }
      ],
      "extensions": {}
    }
  ]
}

I also created a public report just for this test to let you try it out. This is the repo: https://github.com/koo27/defer-stream-test
I set up a urql client too, but I get the same response anyway.

What am I doing wrong?

Hey! @koo27 to use defer and stream you need to use experimental release from graphql-js https://github.com/graphql/graphql-js/releases/tag/v16.1.0-experimental-stream-defer.6 for new major release of graphql-yoga we plan to provide out of box support #1352
