__typename is not returned when queried

[cwheel]

In a query like the following:

query {
   Hero {
      __typename
   }
}

The expected response would contain a key like:

"__typename": "Hero"

Instead, the __typename key is omitted from the response. I've done a bit of poking around in Juniper, and it seems that the concrete_type_name function is called to determine the value __typename should resolve when queried. Wundergraph appears to define that function here, but to no effect. Any thoughts on what might be happening here? Thanks!

Hero expects a primaryKey parameter:

concrete_type_name is unused yet.

Right, that query above was a (poor) example. However, in the example you provided, I'd expect the response to be:

"data": {
   "Hero": {
       "__typename": "Hero"
    }
}

I'm also not quite sure I understand what you mean by being unused. As I understand it, concrete_type_name is something Juniper expects to be implemented.

Please, ignore my silly remark regarding concrete_type_name

Got it, so if Wundergraph is implementing concrete_type_name, shouldn't Juniper be able to resolve __typename?
