TypeSafe Client how to use List of Ids

[robp94]

How to have a List of Ids as Parameter.
For the server, I can do something like this:

@NonNull
fun getByIds(@Id @NonNull ids: List<String>): Uni<List<Order>> {

(kotlin not tested in java, but should be similar)
which results in graphql like this:

"Query root"
type Query {
  _entities(representations: [_Any!]!): [_Entity]!
  _service: _Service!
  getByIds(ids: [ID]!): [Order]!
}

But if I create a Client with Java or Kotlin like this:

    Uni<List<Order>> getOrdersByIds(@Id @NonNull List<String> ids);

I get an error

GraphQlClientException: errors from service
errors:
- Error{message=Validation error of type VariableTypeMismatch: Variable type 'ID!' doesn't match expected type '[ID]!' @ 'getOrdersByIds', locations=[{line=1, column=55}], path=null, extensions={queryPath=["getOrdersByIds"], description=Variable type 'ID!' doesn't match expected type '[ID]!', classification=ValidationError, validationErrorType=VariableTypeMismatch}})

I can't put the Annotation inside the list like:

Uni<List<OrderGQL>> getOrdersByIds(@NonNull List<@Id String> ids);

Since the target is not allowed.

Without the Id Annotation, it does work.

From the code it looks good, I will try to test it later or tomorrow.

I only have quarkus based tests. The current quarkus version seems not to work with the branch, so I can't test it.

If it is possible to get a schema with list of IDs in the client, it should be fine:

ids(list: [ID]): String
