@ResolveReference() not supported

[psteinroe]

Hi,

it seems like that the @ResolveReference() decorator is currently not supported. It is not picked up and added to the server.

I am trying to work on that, but if you have any idea where the problem is let me know! :)

Yes you're right.
We use @graphql-tools/schema makeExecutableSchema (or to be more precise, @nestjs/graphql uses it) to create the schema but it doesn't support graphql properties like __resolveReference, that's why apollo (and @nestjs/graphql GraphQLFederationModule) uses a custom function buildFederatedSchema to add this props.

We should manually add them in our GraphQLFactory somewhere before the transformFederatedSchema.

or as a nasty fix maybe we could simply call @nestjs/graphql GraphQLFederationFactory.mergeOptions instead of the simple GraphQLFactory one and then use the Apollo buildFederatedSchema function.

@ResolveReferenceLoader should not be affected by all of this and should keep working as always

So this means I can use @ResolveReferenceLoader instead of @ResolveReference for a working schema?

[Davide-Gheri]

@vabatta yes, exactly.
