[import] Couldn't find type link in any of the schemas

[klippx]

Hello,

I am trying to use #import syntax in my federated schema:

import path from 'path';
import * as url from 'url';
import { buildSubgraphSchema } from '@apollo/subgraph';
import { processImport } from '@graphql-tools/import';
import { resolvers } from './resolvers/index.js';

const __dirname = url.fileURLToPath(new URL('.', import.meta.url));

export const buildSchema = async () => {
  const schemaFile = path.join(__dirname, '../schema.gql');

  // I want this to resolve "#import" statements, but instead
  // this fails with: "Couldn't find type link in any of the schemas"
  const typeDefs = processImport(schemaFile);

  return buildSubgraphSchema({
    typeDefs,
    resolvers,
  });
};

It doesn't seem to handle the "link" dependecy which is a federated directive. They would normally be "fixed" by buildSubgraphSchema which comes only later...

How do I get these two libs to work together?

The latest version 7.0.9 of @graphql-tools/import solves the issue with link, but it gets stumped by the imported (linked) directives.

For example, let's say the schema is:

#import CarComponentType from '../../shared/graphql/schema.gql'

schema
  @link(
    url: "https://specs.apollo.dev/federation/v2.6"
    import: [
      "@key"
      "@external"
      "@provides"
      "@requires"
      "@extends"
      "@shareable"
      "@tag"
      "@inaccessible"
      "@override"
    ]
  ) {
  query: Query
  mutation: Mutation
}

"""
Base for all Car related information in the graph.
"""
type Car
  @key(fields: "carKey")
  carKey: CarKey!
  allGlobalFeatures: [GlobalFeature!]! @inaccessible
}

Then the error is about inaccessible now:

Error: Couldn't find type inaccessible in any of the schemas.
