[bug]: Score field is missing in the Recommendation API response

[scpatricklim]

Description

According to the documentation https://www.algolia.com/doc/rest-api/recommend/#tag/recommendations/operation/getRecommendations the recommendation API response returns both the _score field and objectID as mandatory fields however we encounter the _score field being empty which breaks our validation.

This can be reproduce by calling getRecommendations on a newly added record prior retraining the model.

Can you advise is this an expected behaviour and the _score field is expected to be optional ?

Language

All

Client

All

Steps to reproduce

1. Add a new record to the index via the SaveObject method

client, err := search.NewClient(appID, apiKey)
if err != nil {
    panic(err)
}
// Add record to an index
saveResp, err := client.SaveObject(
    client.NewSaveObjectRequest(indexName, record),
)

2. call the recommendation API on the same record.
3. inspect the response which doesn't contains the _score field

Relevant log output

No response

Self-service

• I'd be willing to fix this bug myself.
