How to use fields[profile] while requesting events in API v2?

Hi there,

We’re migrating our integration with Klaviyo to v2 and I faced the issue with retrieving such profile properties as first_name, last_name, email when collecting events.

API reference declares optional query param “fields[profile]”: https://developers.klaviyo.com/en/reference/get_events

But when I try to use this param:

GET https://a.klaviyo.com/api/events?sort=datetime&fields[profile]=first_name,last_name,email&filter=greater-or-equal(datetime,2022-10-20)

I got the error 400 Bad Request:

{
    "errors": [
        {
            "id": "cc99c0e8-a548-43ed-827b-793d82f78aad",
            "status": 400,
            "code": "invalid",
            "title": "Invalid input.",
            "detail": "'profile' is not an allowed field family for this resource.",
            "source": {
                "parameter": "fields"
            },
            "meta": {}
        }
    ]
}

Please advise how I can retrieve profile properties from /events endpoint? I would like don’t requesting /profiles endpoint for a some reasons.

Thanks in advance!
