[Node(NodeResolver="...")] does not work with [UseFirstOrDefault]

[fredrik-stock]

Describe the bug When pointing [Node]'s resolution for type T towards a method tagged with [UseFirstOrDefault] that returnsIQueryable<T>, resolution fails somewhere down in InterfaceType.CompleteAbstractTypeResolver() (presumably) because none of the types in the schema match IQueryable<T>.

To Reproduce

Code

[Node(NodeResolverType = typeof(ClientResolver), NodeResolver = "GetClient")]
public class Client
{
    public int Id { get; set; }
    // <snip>
}

public class ClientResolver
{
    [UseFirstOrDefault, UseProjection]
    public static IQueryable<Client> GetClient(int id, HotChocolate.Resolvers.IResolverContext resolverContext)
        =>resolverContext.Service<IDbContextFactory<DataDbContext>>().CreateDbContext().Clients.Where(c => c.Id == id);
}

Query

{
    node(id: "Q2xpZW50Cmky") { 
        id
    }
}

Result

{
  "errors": [
    {
      "message": "Could not resolve the actual object type from `System.String` for the abstract type `Bar`.",
      "locations": [
        {
          "line": 2,
          "column": 3
        }
      ],
      "path": [
        "node"
      ]
    }
  ],
  "data": {
    "node": null
  }
}

Expected behavior Expected the resolution to apply the [UseFirstOrDefault] middleware to translate the collection from IQueryable<T> to T.

Desktop (please complete the following information):

• OS: Windows
• Version: 10

HotChocolate

• Packages: HotChocolate.AspNetCore, HotChocolate.Data.EntityFramework
• Version: 11.1.0-preview.69

Additional context The exact same method (GetClient()) exposed directly as the query client(id: ID!) works as expected.

The method also works as a node resolver if [UseFirstOrDefault] is removed and changed to return ...Clients.FirstOrDefaultAsync(...), but then projection is no longer possible.

I do not know if [UseProjection] would be applied if the query worked, or if that middleware is also skipped during node resolution.

In addition it appears the message resource ErrorHelper_ValueCompletion_CouldNotResolveAbstractType_Message is missing the interpolation variables. System.String and Bar are not what is supplied to it.
