How do you make __typename required in type when fetching it explicitly?

[ericbf]

So I have a union type that I discriminate by the __typename property. The problem I’m seeing is that in the generated types for my query where I fetch __typename from the union type, __typename is optional. It shouldn’t be optional in the return type since I’m expressly getting it through my query:

query SomeQuery {
    someUnion {
        __typename
    }
}

Results in a return type with __typename as optional, even though I’m specifically requesting it.

So how do I make the __typenames not optional (i.e., required)?

add this to your config nonOptionalTypename: true I think there might be a bug for us to fix here 🤔

I think it is likely a regression.

that can act as workaround for now until we land a fix here #8793

@ericbf what does your config look like I am trying to repro this?

[ericbf]

I’ll create a repro
