HI I am using this group by query for our filters

curl --location --request GET '{{URL}}/collections/job_title/documents/search/?highlight_fields=none&page=1&per_page=20&q=developer&query_by=job_title&sort_by=count:desc&group_by=job_title: desc&prioritize_exact_match=true' \
--header 'X-TYPESENSE-API-KEY: {{KEY}}'

but I am getting this error, any idea what I am missing here.

{
  "message": "Could not find a field named `count` in the schema for sorting."
}

cause if I remove the sort by field I get this response
