Steps to reproduce

Add Resolve field of ObjectType using ParentRequires to schema:

        var executor = await new ServiceCollection()
            .AddGraphQL()
            .AddQueryType(q => q
                .Field("foo")
                .Resolve(ctx => new[] { new Foo { Bar = new() } }.AsQueryable())
                .UseProjection()
                )
            .AddObjectType<Foo>(c =>
            {
                c.Field(f => f.Bar);
                c.Field("quux")
                    .Resolve(c => c.Parent<Foo>().Bar)
                    .ParentRequires<Foo>(f => f.Bar!);
            })
            .AddProjections()
            .BuildRequestExecutorAsync();

Query the field foo.quux.bar and get an NRE in reponse
