Product

Hot Chocolate

Version

16.0.9

Link to minimal reproduction

https://github.com/ChilliCream/graphql-platform/blob/1063f8bde76509c1e6cbf36e034a63cc40c51b21/src/HotChocolate/Core/src/Types/Types/Directives/DirectiveTypeInterceptor.cs

Steps to reproduce

1. Set up GraphQL with .AddApolloFederation():

builder.Services.AddGraphQLServer()
.AddApolloFederation()
.AddTypes()
.AddFiltering()
.AddSorting()
.AddPagingArguments();

2. Create query with paging

[QueryType]
public static partial class EmployeeResolver
{
      [UseConnection]
      public static async Task<PageConnection<Employee>> GetEmployeeByPageTest(AppDbContext db, QueryContext<Employee> query, PagingArguments args)
      {
          var page = await db.Employees.With(query).OrderByDescending(e => e.EmpId).ToPageAsync(args);
          return new PageConnection<Employee>(page);
      }
}

3. Build and run applicationl; it crashes and fails to start.

What is expected?

The application runs and you can run the query with paging.

What is actually happening?

The application is crashing on startup.
