Can't federate AWS Appsync if there is a custom type `AWSDateTime` #2607

I am trying to use Apollo Federation to connect subgraph from AWS Appsync. When I start federation I got this error: UNKNOWN: Unknown type AWSDateTime. It seems Federation doesn't recognise AWS Scalar type AWSDateTime. Is there a way to extend Apollo federation to support Appsync types?

Hi. Federation is no tailor made support for appsync per-se, but you can declare whichever scalar you want in our subgraphs, so I'd assume that you'd just need to add scalar AWSDateTime to one of your subgraph (plus the definition of any other type appsync seems to require; I'm not familiar with appsync at all btw).
