@Provides Directive Unexpected Error

Reproduction Repo: https://github.com/ksaldana1/provides-fed-repro

I am pretty confused by what I am seeing here. I followed the example from the docs, and from what I can tell the structure I have isn’t any different from the example provided in the federation-demo, but maybe I’m missing something really obvious.

Despite me labeling my fields, I’m still getting error messages such as : UnhandledPromiseRejectionWarning: GraphQLSchemaValidationError: [users] Kitchen.name -> is marked as @external but is not used by a @requires, @key, or @provides directive.

This was happening on a larger project and seemed to continue when I scaled it down.

Thanks for all your hard work! Federation is really awesome!

Thanks for getting this fixed @JakeDawkins ! The first time I read through the federation docs I thought “I don’t think I’ll need these advanced features…”, but then after I grokked them it felt hard to live without. So thanks for being one step ahead on the features!

Thanks! I’ve just found out my error was due to my own ignorance. I forgot to specify the @key directive on the type I’m extending. When including that it resolved my issue.
