Website: Schema-first example for Mutations page contains incorrect schema

[seclerp]

This page (Schema-first approach tab) contains incorrectly defined BookInput type. It should be declared as input, not as type, because nested types inside inputs could be only input types and not object types.

Need to be changed from this:

type BookInput {
  title: String
  author: String
}

To this:

input BookInput {
  title: String
  author: String
}
