Current behavior

Having a base @ObjectType({ isAbstract: true }) class decorated with @Directive('@key(fields: "id")') does not apply that directive to inherited classes.

Minimum reproduction code

N/A

Steps to reproduce

1. Copy sample 31 for code-first federation.
2. Add a model.base.ts to users-application/src/users/models:

   @ObjectType({
   isAbstract: true,
   })
   @Directive('@key(fields: "id")')
   export class ModelBase {
   @Field((type) => ID)
   id: number;
   }

3. Update the user.model.ts:

   @ObjectType()
   export class User extends ModelBase {
   @Field()
   name: string;
   }

4. Start the projects (gateway last)
5. See the error in the gateway console

Expected behavior

The directive is applied to all inheriting classes.

Other

• Tried with both federation 1 and 2.
• I presume this is an issue not specifically related to federation, but I do not know enough about directives to test other configurations for now.
• I have tested this with the (currently) latest versions in my own project with the same results:

  "@apollo/server": "^4.9.1",
  "@nestjs/apollo": "^12.0.7",
  "@nestjs/graphql": "^12.0.8",
