Nexus: Argument of type 'NexusObjectTypeDef<"Node">' is not assignable to parameter of type 'NexusInterfaceTypeDef<string>'.

Following the getting started example from the docs almost exactly:

I am unable to reference the Node type in my account type.

Gives me the tslint error of

Argument of type 'NexusObjectTypeDef<"Node">' is not assignable to parameter of type 'NexusInterfaceTypeDef'.
Property 'config' is protected but type 'NexusObjectTypeDef' is not a class derived from 'NexusInterfaceTypeDef'.ts(2345)

And a console error of

I can get everything to work just fine if I do not attempt to implement the Node type and instead just specify the 'id' field manually.

Any idea why I am not able to implement Node as illustrated in the docs?

Here are my package versions:

"graphql": "^14.1.1",
    "graphql-yoga": "^1.17.4",
    "knex": "^0.16.3",
    "lodash": "^4.17.11",
    "nexus": "^0.9.9",
    "pg": "^7.8.0"

Thank you. Seems like a very promising project!

Got it working if I swap Node from objectType to interfaceType. Also had to provide a t.resolveType(() => null); to it's definition.

resulting in:

export const Node = interfaceType({
  name: "Node",
  definition(t) {
    t.id("id", { description: "Unique identifier for the resource" });
    t.resolveType(() => null);
  }
});

Perhaps the example code on https://nexus.js.org/docs/getting-started needs to be updated?

Thanks for the report! Yes the docs were indeed wrong here, pushed a fix that should update them shortly!
