GraphQL .NET Mutations with Nested InputObjectGraphType

Question

Within GraphQL-Dotnet i have a mutation with a list type input type, and within that type, i have a list of items, which themselves are an input type.

I have defined the mutation and the resolver for the mutation to be:

            Field<ListType>("createList")
                .Argument<NonNullGraphType<ListInputType>>("list")
                .ResolveAsync(async context =>
                {
                    var list = context.GetArgument<ListEntity>("list");
                    var val = await dataContext.AddAsync(list);
                    await dataContext.SaveChangesAsync();
                    return val.Entity;
                });

And my list type is defined as

    public class ListInputType : InputObjectGraphType<ListEntity>
    {
        public ListInputType()
        {
            Name = "listInput";

            Field(f => f.Key).Description("list key");
///...
            Field<ListGraphType<ListItemInputType>>("items").Resolve(f =>
            {
                return null;
            });
        }
    }

I am expecting to be able to put a break point within the resolve, and examine what is going on within the resolve, so that i can finish mapping up the list items, so i am able to then have EF within the mutation definition, save both the new list its self, as well as the items.

The breakpoint never gets hit.

I have also tried Field(f => f.ListItems) on its own instead of the Field<ListGraphType<ListItemInputType>>... line, and that creates a schema for me, but i get hidden crashes and exceptions that cannot be caught when i attempt to push the mutation.

All i am looking to do is the following:


mutation {
  createList(list: {
    key: "new_list",
    items: [
      {
        alias: "alias1",
        order: 1
      },
      {
        alias: "alias2",
        order: 2
      },
      {
        alias: "alias3",
        order: 3
      }
    ]
  }) {
    id
  }
}

But i dont seem to be able to figure it out or find the answer anywhere on here or google.
