This is an AspNetCore 6.0.11
Operating system version:
macOS Ventura 13.0.1 (22A400)
Description of the problem including expected versus actual behavior:
Cannot set Sort order in SortOptionsDescriptor<T>
Steps to reproduce:
var response = await client.SearchAsync<SomeType>(
s => s
.Index("...")
.Size(100)
.Sort(
srt => srt.Field(
f => f.SomeFieldHere,
cfg => cfg.Order(SortOrder.Desc)
)
), cancellationToken
);
The above compiles fine. When invoked at runtime, there is an exception:

If I omit the FieldSortOrderDescriptor (i.e., the second argument), everything works as expected. But then, how can I specify the sort order?
Surely, I am doing something wrong.
