graphql-import does not work with Apollo Federation

[villesau]

HI, when building federated schema using basic builiding blocks, following error is thrown:

error: Uncaught exception: (message=Directive key: Couldn't find type key in any of the schemas., stack=Error: Directive key: Couldn't find type key in any of the schemas.
    at collectDirective (/Users/user/code/node_modules/graphql-import/src/definition.ts:172:15)
    at Array.forEach (<anonymous>)
    at collectNewTypeDefinitions (/Users/user/code/node_modules/graphql-import/src/definition.ts:86:30)
    at Object.completeDefinitionPool (/Users/user/code/node_modules/graphql-import/src/definition.ts:49:39)
    at Object.importSchema (/Users/user/code/node_modules/graphql-import/src/index.ts:127:18)

The type that causes the issue looks like this:

type SomeType @key(fields: "id") {
  id: ID!
}

key directive is something that glues different pieces of extended types together when federating schema. See the documentation for further details: https://www.apollographql.com/docs/apollo-server/federation/core-concepts/

Could the validation be loosened on import-schema library so that key would not cause exception?

Hi @villesau !
In 1.0.0 beta release, we introduced a lot of changes including apollo federation support;
Could you install graphql-import@beta to try new changes? Don't forget to modify your code regarding to the migration notes in README.

Thanks @ardatan ! Unfortunately we postponed our federation plans so I'm not able to test it any time soon. I hope someone else who has faced this issue can report back if the changes works for them!
