HotChocolate with Postgres: how to map NpgsqlRange type?

[Arsync]

I have models with properties of type NpgsqlRange<>. When project is started, it throws following errors:

HotChocolate.SchemaException: 'For more details look at the Errors property.

1. Unable to infer or resolve a schema type from the type reference NpgsqlRange<Instant!> (Output).
2. Unable to infer or resolve a schema type from the type reference NpgsqlRange<LocalDate!> (Output).

For now I've created graphql model types, where these properties are ignored. But this cannot last forever.

@Arsync the easiest thing is to define a ObjectType<NpgsqlRange<LocalDate!>> and ObjectType<NpgsqlRange<Instant!>> and register them on the schema.

Thanks! Now I have

public class InstantRangeType : ObjectType<NpgsqlRange<Instant>>
{
    protected override void Configure(IObjectTypeDescriptor<NpgsqlRange<Instant>> d)
    {
        d.BindFieldsExplicitly();

        d.Field(x => x.LowerBound);
        d.Field(x => x.UpperBound);

        d.Field(x => x.IsEmpty);
    }
}

It runs and query looks like

query GetPerson($personId: Int!)
{
  person(personId: $personId)
  {
      versionPeriod {
        lowerBound
        upperBound
      }
  }
}

But there is exception while executing the query:

The binary operator NotEqual is not defined for the types 'NpgsqlTypes.NpgsqlRange`1[NodaTime.Instant]' and 'System.Object'.

Are you using projection? what version of HC are you on?

[Arsync]

Yes, I'm using projection, HC version 13.0.5
When UseProjectionAttribute is disabled, query done without any exceptions.
Any chance to use it with projections?
