graphql-platform: Error SS0006 when custom scalar type begins with lowercase letter (and used as query argument)

Is there an existing issue for this?

Describe the bug

UPDATE Changing title to reflect that this is happening for any custom scalar that begins with a lowercase letter. Does not appear to have anything to do with Hasura or uuid.

I am attempting to use StrawberryShake with a Hasura endpoint. Fully appreciate that this is pretty bleeding edge, thank you for building an alternative to graphql-dotnet.

Hasura uses a custom scalar for uuid, and I’m running into problems when authoring queries that accept it as an argument. I’ve attached the schema file generated from a fresh Hasura instance with a single items table. This table only has two columns: id (uuid) and name (text). For testing I added two rows only: “foo” and "bar.

schema.graphql.txt

Attempting to build this query, with or without using it, results in a SS0006 error:

query GetItemsById($item_id: uuid!) {
  items(where: {id: {_eq: $item_id}}) {
    id
    name
  }
}

I am able to use a nearly identical query to get items by name successfully:

query GetItemsByName($item_name: String!) {
  items(where: {name: {_eq: $item_name}}) {
    id
    name
  }
}

Here is the test client I used:

using System;
using System.Threading.Tasks;
using Microsoft.Extensions.DependencyInjection;

namespace ss_test
{
    class Program
    {
        static async Task Main(string[] args)
        {
            var serviceCollection = new ServiceCollection();

            serviceCollection
                .AddTestClient()
                .ConfigureHttpClient(client => client.BaseAddress = new Uri("http://localhost:8080/v1/graphql"));
            
            IServiceProvider services = serviceCollection.BuildServiceProvider();

            ITestClient client = services.GetRequiredService<ITestClient>();

            var result = await client.GetItems.ExecuteAsync();
            foreach (var item in result.Data.Items)
                Console.WriteLine(item.Name);
            
            var result2 = await client.GetItemsByName.ExecuteAsync("foo");
            foreach (var item in result2.Data.Items)
                Console.WriteLine(item.Name);

            // FIXME: simply including GetItemsById.graphql in build produces this error:
            //        CSC : error SS0006: Sequence contains no matching element
            //var result3 = await client.GetItemsById.ExecuteAsync("c52dbb49-f578-473d-91c4-dd1212753c46");
            //foreach (var item in result3.Data.Items)
            //    Console.WriteLine(item.Name);
        }
    }
}

Steps to reproduce

1. Start clean Hasura dev instance using docker container
2. Add single table items with columns: id (uuid auto) and name (text)
3. Add two rows: foo, bar
4. Follow console StrawberryShake tutorial
5. Attempt to build query to get items by id (see bug description)
