Describe the bug

I have a issue in my microservice with use Hot Chocolate: when i try to expose the schema have problems because the filed service is not created and in the documentation i dont have information about that. this is the type City that i implement 👍
`public class CityType : ObjectType<Data.City>
{
protected override void Configure(IObjectTypeDescriptor<Data.City> descriptor)
{
descriptor.Field(x => x.Id).Type();
descriptor.Field(x => x.Code).Type();
descriptor.Field(x => x.CountryIso).Type();
descriptor.Field(x => x.SubdivisionIso).Type();
descriptor.Field(x => x.Name).Type();
descriptor.Field(x => x.Timezone).Type();
descriptor.ExtendServiceType<Data.City>();

    }
   
}`

and startup:
services.AddGraphQLServer()
.AddType()
.AddQueryType()
.RegisterService<ICityService>();

Steps to reproduce

1. define a data model with the attributes with city

2. define a query class in c# this have one parameter IserviceCity ` public class CityQuery
   {
   [UseServiceScope]
   [UsePaging(SchemaType = typeof(CityType))]
   [UseSelection]
   public async Task<List<Data.City>> GetAllCity([Service(ServiceKind.Synchronized)] ICityService cityService)
   {

        var listcities = await cityService.SelectAsync();
   
        return  listcities.Select(x => new Data.City() { Id = x.Id,Code=x.Code, CountryIso = x.CountryISO, Name = x.Name,SubdivisionIso= x.SubdivisionISO, Timezone=x.timezone }).ToList();
    }
   

   }`
   3.create apollo gateway with apollo federetion in node js

Relevant log output
