@flochaz could you help us out with updating AppSync test integration with the latest schema changes?

I can't make @requires to work and looks like it's the same for a many other implementation: The first reason seems to be that the docker hub image used in docker-compose for users service (apollo-federation-implementations/users) does not implement new schema (especially yearsOfEmployment). But even using local implementation (https://github.com/apollographql/apollo-federation-subgraph-compatibility/tree/main/subgraphs/users) I end up with the following error, any suggestion ?

{
  "data": {
    "product": {
      "createdBy": {
        "averageProductsCreatedPerYear": null
      }
    }
  },
  "errors": [
    {
      "message": "invalid content: Missing key `_entities`!",
      "locations": [],
      "path": [
        "product",
        "createdBy"
      ],
      "extensions": {
        "type": "ExecutionInvalidContent",
        "reason": "Missing key `_entities`!"
      }
    }
  ]
}

👋 Make sure to pull in the latest main and rebuild it locally using npm run setup - apollo-federation-implementations/users does implement the latest schema.

In order to test averageProductsCreatedPerYear make sure to run your queries through the router, since it @requires(fields: "totalProductsCreated yearsOfEmployment") those fields will only be populated if request flows through the router.
