Hey 👋 I'm using apollo to generate an introspected schema json from an SDL, but when I try to feed the json into a tool like GraphiQL or GQL voyager, I get an error

buildClientSchema.mjs:193 Uncaught Error: Introspection result missing interfaces: { kind: "OBJECT", name: "issue__c", fields: [[Object], [Object], [Object]] }.

Does anyone know what might be going on here? as far as I can tell, the SDL is valid (can feed sdl into voyager and see visualization). I've attached the introspection blob in case that helps. Appreciate any ideas 🙏

An introspection schema json is the raw result of an introspection GraphQL query. There are several possible ways to write such a query, which will result in different shapes of the response. It is possible that this json response doesn't correspond to the query made by these tools and so they can't find what they're looking for in it.

🤔 is there a way to feed that query into the

._toIntrospectionSchema_()

call? otherwise I'm not sure how to generate this

interfaces

is of a nullable type. Yes it may be something like this!

interesting... I see that under the hood, there is a

IntrospectionSchemaBuilder

seems like that would be the only way to get in the weeds w/ this schema generator, but it is private

ah we do use

explicitNulls = false

, it's probably that?

schema = schema.copy(
                    __schema = schema.__schema.copy(
                        types = schema.__schema.types.map {
                            if (it is IntrospectionSchema.Schema.Type.Object) {
                                it.copy(
                                    interfaces = emptyList()
                                )
                            } else {
                                it
                            }
                        }
                    )
                )

kinda gross but this solves it... now I get a new error 😄

you may still have other issues however if... ah 😄

ty for the help! 🙌

sure thing!

think you guys might want to consider adding

encodeDefaults = true

to the json serializer. Reason being, that if you don't things like

Field.args

which default to an empty array will not be included in the encoded result

but

args

is not nullable

yes 🙂

indeed!

nothing hits like 1 line open source cred 😈

it may be a bit more than 1 line because of tests 😛

haha no worries... will see how many things I break some time today 🙂
