Proactive feedback

Use the top-level entry extensions to send data concerning deprecations and warnings in the response to the query.

For instance, the following query exports two fields using the same dynamic variable name "prop", which generates a warning:

query {
  posts {
    excerpt @export(as: "prop")
    content @export(as: "prop")
  }
}Copy

The response will include section warnings (under extensions) with a corresponding message:

{
  "extensions": {
    "warnings": [
      {
        "message": "Dynamic variable with name 'props' had already been set, had its value overridden",
        "locations": [
          {
            "line": 4,
            "column": 25
          }
        ]
      }
    ]
  },
  "data": {
    "posts": {
      "excerpt": "Hello world!",
      "Content": "<p>Hello world!</p>"
    }
  }
}Copy

​

Deprecations

Deprecations are returned in the same query involving deprecated fields, and not only when doing introspection.

​

Warnings

Warning are issues which can be considered non-blocking, i.e. they enhance the query but do not break it.
