Setup

const apolloServer = new ApolloServer({
  gateway,
  subscriptions: false,
  engine: {
    apiKey: config.get('engine.apiKey'),
    schemaTag: config.get('appEnv'),
  },
})

const gateway = new ApolloGateway({
  buildService({ name, url }) {
    switch (name) {
      case config.get('services.first.name'):
        return new SomeApiDataSource({ url })
      case config.get('services.second.name'):
        return new AnotherApiDataSource({ url })
    }
  },
)

Note that I have ENGINE_API_KEY ENV set and I also pass it to the server initializer.

@rtymchyk I’ve got a reproduction of this now, working on identifying the issue and putting together a fix.

@trevor-scheer so there are no composition errors, this was basically a service push that is no-op since the graph did not change. I think I’m just reading too much into that message, will check this out again on deploy with actual graph changes and see. Thanks for your response and help with everything.
