Federation Gateway cannot find schema in managed mode

[mmuth]

Hi all,

I am simply trying to start the Apollo Gateway in the managed mode. I pushed my schema to the Graph Manager using the CLI and now try to connect via the ENGINE_API_KEY... My code is more or less just

const server = new ApolloServer({
    gateway,
    subscriptions: false,
    engine: {
        apiKey: 'service:....:.....'
    },
    context: ({ req }): HeaderContext => ({ headers: req.headers })
});

The problem I get is:

[WARN] Sun Feb 02 2020 23:15:43 GMT+0100 (Central European Standard Time) apollo-gateway: Error checking for schema updates. Falling back to existing schema. Error: CachedFetcher: Could not fetch <?xml version='1.0' encoding='UTF-8'?><Error><Code>AccessDenied</Code><Message>Access denied.</Message><Details>Anonymous caller does not have storage.objects.get access to engine-partial-schema-prod/SOME_SECRET.../current/v1/composition-config-link.</Details></Error>

I also debugged this. It connects to GCP using the hashed API key and downloads a secret JSON (this works), but then it tries to download a link file under https://storage.googleapis.com/engine-partial-schema-prod/SECRET..../current/v1/composition-config-link which fails. Is this a misconfiguration of Apollo at Google Storage or am I doing something wrong ?

Cheers

Allright, found the Solution by myself. For anyone stumbling over that same problem: my Mistake was that I pushed my Schema to the Graph Manager via the apollo-cli WITHOUT a serviceName specified.

If I added that like apollo-cli service:push --serviceName=myservice ... then it worked smoothly. The Exception occurring here is quite unhelpful though.

Having the same issue. Should this need to be set if apollo.config.js is set?
