Strawberry Shake

Describe the bug

Based on Demo project from docs I prepared project pointing to my endpoint and using my query. I'm using .NET 7.

I had to remove JSON scalar from schema because of other bug: https://github.com/ChilliCream/graphql-platform/issues/5899 to make it work.

Repository: https://github.com/kpiekara/crystallize-example/blob/main/Demo

Schema: https://github.com/kpiekara/crystallize-example/blob/main/Demo/schema.graphql

Query: https://github.com/kpiekara/crystallize-example/blob/main/Demo/GetItem.graphql
Most interesting part:

query GetItem ($language: String!, $path: String!) {
    catalogue(language: $language, path: $path) {
        ...on Product {
            ...product
            topics {
                path
                name
            }
        }
    }
}

fragment product on Product {
    id
    name
    type
    language
    path

    components {
        ...component
    }

    variants {
        name
        sku
        components {
            ...component
        }
        price
        priceVariants {
            identifier
            name
            price
            currency
        }
        stockLocations {
            identifier
            name
            stock
        }
        isDefault
        images {

            variants {
                key
                width
                url
            }
        }

        subscriptionPlans {
            identifier
            name
            periods {

                initial {
                    priceVariants {
                        identifier
                        name
                        price
                        currency
                    }
                }
                recurring {
                    priceVariants {
                        identifier
                        name
                        price
                        currency
                    }
                }
            }

Generated client:

[global::System.CodeDom.Compiler.GeneratedCode("StrawberryShake", "13.2.1.0")]
public partial interface IGetItemResult
{
    public global::Demo.IGetItem_Catalogue? Catalogue { get; }
}

[global::System.CodeDom.Compiler.GeneratedCode("StrawberryShake", "13.2.1.0")]
public partial interface IGetItem_Catalogue
{
}

[global::System.CodeDom.Compiler.GeneratedCode("StrawberryShake", "13.2.1.0")]
public partial interface IGetItem_Catalogue_Document : IGetItem_Catalogue
{
}

[global::System.CodeDom.Compiler.GeneratedCode("StrawberryShake", "13.2.1.0")]
public partial interface IGetItem_Catalogue_Folder : IGetItem_Catalogue
{
}

[global::System.CodeDom.Compiler.GeneratedCode("StrawberryShake", "13.2.1.0")]
public partial interface IGetItem_Catalogue_Product : IGetItem_Catalogue
{
    public global::System.Collections.Generic.IReadOnlyList<global::Demo.IGetItem_Catalogue_Topics>? Topics { get; }
}

For code:

var client = services.GetRequiredService<Icatalogue>();
var result = await client.GetItem.ExecuteAsync("", "");
result.EnsureNoErrors();
result.Data.Catalogue.

Catalogue has no properties.

var client = services.GetRequiredService<Icatalogue>();
var result = await client.GetItem.ExecuteAsync("", "");
result.EnsureNoErrors();
(result.Data.Catalogue as IGetItem_Catalogue_Product).

Catalogue has only 'Topics' property.

Steps to reproduce

1. Clone repository
2. Build

Additional Context?

No response

Version

13.2.1

Clone and build the linked Demo repository, then inspect schema.graphql, GetItem.graphql, and the generated IGetItem result interfaces. Compare the selected Product fields with the generated Catalogue properties and investigate why only Topics is emitted. Done means the generated client exposes the requested Product selection and the reproduction query returns the expected data.
