prisma's SDL is somewhat different from the spec... i have this:

type Query {
  id: ID! @id
  thing: [Thing!]!
}

and getting:

The type

Query

has is using a reserved type name. Please rename it.

you can only extend type Query, as there are few core types such as Query, Mutation, Subscription I believe what you are trying to do is create a new type Thing:

type Thing {
    id
    thing: Thing
}

and then in resolvers either create resolver or forward to db

[this example](https://www.prisma.io/docs/get-started/03-build-graphql-servers-with-prisma-JAVASCRIPT-e001/#define-graphql-api) has both

Query

and

Mutation
