For anyone that doesn’t want to change the code use the below versions in the parent-level package.json:

  "dependencies": {
    "@apollo/gateway": "^0.28.1",
    "apollo-server": "^2.24.1",
    "graphql": "^15.5.0"
  }

and the below in each of the services’ package.json:

  "dependencies": {
    "@apollo/federation": "^0.25.0",
    "apollo-server": "^2.24.1",
    "graphql": "^15.5.0"
  }

I’m assuming the above errors are thrown because the package.jsons are using “latest” when they should be locked down to v1 when this demo was written. Federation v2 was just released and I’m assuming these package.jsons are pulling down v2. My versions aren’t the latest for v1 but will at least make their code functional.

extend type .... is not working (anymore?) you need to use the @extends directive. This is really badly documented.

extend type User @key(fields: "id") {
    id: ID! @external
    username: String @external
    reviews: [Review]
  }

becomes

type User @extend @key(fields: "id") {
    id: ID! @external
    username: String @external
    reviews: [Review]
  }

it looks like extend is a reserved keyword to extend type from the same schema definition file
