Hello, I'm new to Typesense and I'm trying to do a search and sort the results by proximity to a geopoint. When I do my search using the Ruby client, like this:

client.collections["users"].documents.search(
   q: "Paul",
   query_by: "name",
   sort_by: "location(38.879140, -76.981880):asc:asc"
 )

I get this error:

ETHON: performed EASY effective_url=<http://localhost:8108/collections/users/documents/search?q=Paul&query_by=name&sort_by=location%2838.879140%2C%20-76.981880%29%3Aasc%3Aasc> response_code=404 return_code=ok total_time=0.004434
/Users/paul/.rbenv/versions/3.3.4/lib/ruby/gems/3.3.0/gems/typesense-2.0.0/lib/typesense/api_call.rb:100:in `block in perform_request': Could not find a field named `location(38.879140, -76.981880):asc` in the schema for sorting. (Typesense::Error::ObjectNotFound)

But when I look a the schema:

puts JSON.pretty_generate(client.collections["users"].retrieve)

{
  "created_at": 1726775082,
  "default_sorting_field": "",
  "enable_nested_fields": false,
  "fields": [
    {
      "facet": false,
      "index": true,
      "infix": false,
      "locale": "",
      "name": "name",
      "optional": false,
      "sort": false,
      "stem": false,
      "store": true,
      "type": "string"
    },
    {
      "facet": false,
      "index": true,
      "infix": false,
      "locale": "",
      "name": "location",
      "optional": true,
      "sort": true,
      "stem": false,
      "store": true,
      "type": "geopoint"
    }
  ],
  "name": "users",
  "num_documents": 222801,
  "symbols_to_index": [],
  "token_separators": []
}

It looks like I have a field named location that is a geopoint and has sort set to true. Does anyone know why this doesn't work?
