Description

I am building a query that has an optional argument

const schema = a.schema({
  sayHello: a
    .query()
    .arguments({
      name: a.string().default("World"),
    })
    .returns(a.string()),
})

However I am encountering this error when attempting to deploy

Failed to instantiate data construct
Caused By: Schema validation failed.\n\nDirective "@default" may not be used on ARGUMENT_DEFINITION.\n\nGraphQL request:7:25\n6 | type Query {\n7 |   sayHello(name: String @default(value: "World")): String \n  |                         ^\n8 | } 

Resolution: See the underlying error message for more details.

with --debug

Directive "@default" may not be used on ARGUMENT_DEFINITION.
  
  GraphQL request:7:25
  6 | type Query {
  7 |   sayHello(name: String @default(value: "World")): String 
    |                         ^
  8 | } 

Instead I would expect

type Query {
  sayHello(name: String = "World"): String
}
