Generator isn't great at reconciling a querys argument types with schema argument types.

[obmarg]

The generator doesn't always do a good job of providing the right argument types if a queries arguments differ in type from where they're provided in a query.

Given the following schema:

input OrderChannelFilter {
  restaurantIdentifiers: [ID!]
  providerIdentifiers: [ID!]
}

type Query {
  orderChannels(filter: OrderChannelFilter): OrderChannel!
}

type OrderChannel {
  id: String
}

and query:

query MyQuery($restaurant_identifier: [ID!]!, $providers: [Provider!]!){
    orderChannels(filter: {
     restaurantIdentifiers: $restaurant_identifier,
     providers: $providers,
  }){
    id
  }

Querygen will try and pass the incorrect tyeps to OrderChannelFilter in it's output. At the very least worth exploring whether querygen can do better here.
