Hmm, this seems to work for me. For eg, try this from one of our demos:

curl -s '<https://qtg5aekc2iosjh93p.a1.typesense.net/multi_search?x-typesense-api-key=8hLCPSQTYcBuK29zY5q6Xhin7ONxHy99>' \
--data-binary '
{
  "searches": [
    {
      "query_by": "name,categories,description",
      "exclude_fields": "vectors",
      "collection": "products",
      "q": "phone",
      "per_page": 1
    }
  ]
}
' | jq

If you remove the

exclude_fields

parameter it will then return the vectors. Could you give me a set of curl commands like this that creates a sample collection, indexes one document, and does a search query that replicates the issue?
