Hi guys, not sure if you're aware of this issue.

I was migrating my gateway implementation to Apollo Server 3.* so started by migrating its graphql endpoints (all good there) but when I was migrating the gateway I realized that it throws an error at runtime:

UnhandledPromiseRejectionWarning: TypeError: Object.values(...).filter(...).flatMap is not a function
[start-service-accounts]     at Object.serverWillStart (C:\Users\vany0\OneDrive\Documentos\GitHub\apollo-client-cache-issue\federation-demo\services\accounts\node_modules\apollo-server-core\dist\plugin\cacheControl\index.js:40:22)

Basically, it is throwing the error here

I had a rough time trying to make it work w/o any luck, so I had to go undo the changes in the gateway and go back to use apollo-server 2.* these are the dependencies I'm using in the gateway:

"@apollo/federation": "0.20.4",
"@apollo/gateway": "0.21.1",
"apollo-server": "^2.19.0",

So by using those dependencies I was able to run the gateway with its endpoints using apollo server 3.*

Any ideas?

@vany0114 you need to bump your node.js version to v12 or higher.

https://www.apollographql.com/blog/announcement/backend/its-here-introducing-apollo-server-3/

We’ve dropped support for Node 8 and 10 (which are no longer in LTS), which lets the TypeScript compiler output more efficient code that takes advantage of newer Node features.
